Description

Overiew
This is an offensive steel core where all the 3 pokemon on the core deal with threats and check each others threats on the core. Heatran with a stall breaker set breaks walls such as chansey,porygon2,toxapex etc that come in the way of AV celesteela. Heatran on the core also provides a valuable fire immunity to the core while also checking threats such as volcarona and Mega charizard Y for the core.
Celesteela on the core with an AV set is used to vastly improve the ground match up since giga drain and Hp Ice takes care of ground teams and AV set allows celesteela to check landorus-I which is a huge threat for steel teams.Celesteela with AV is also a good pivot into special attacks for the core such as vs water teams.Av set functions as Anti-Ground set which improves the match up.
Excadrill on the core is the speed control helping deal with threats like Mega Charizard Y and X,unboosted volcarona, Helping in electric match up and providing electric immunity as well thanks to its part ground typing.Excadrill can also cripple Mega Sableye for the core with toxic thanks to its ability Mold Breaker.

: Offensive heatran set is used here that can set up stealth rock and stall break with magma storm and taunt which completely shuts down walls since taunt prevents recovery moves. Stall breaker set allows heatran to take out walls that may trouble other teammates such as Toxapex,Chansey,Porrygon2 etc. Earth power allows it some decent coverage along with magma storm and it is used to hit opposing heatran and pokemon that resist magma storm such as Toxapex to wear it down. Stealth rock can be set easily since heatran has plenty of resistances and its horrendous weakness to ground is mitigated by air balloon so it can find decent opportunities to set up stealth rock for offensive teammates that appreciate opposing team being worn down.Stone edge can be run in place of stealth rock to check Mega Charizard Y and Volcarona which are otherwise threats to the core.If stone edge is used then 28 evs should be dumped into attack to guarantee OHKO on aforementioned threats[28 Atk / 224 SpA / 4 SpD / 252 Spe ].Toxic can be used in the last slot as wall to cripple walls and wear them down faster in tandem with magma storm.

:This is an AV celesteela set that aims to take out threatening ground types for the core such as landorus and garchomp. It also provides a nice ground immunity to the core and hence it acts as a pivot. Giga drain and Hp ice takes care of most ground types on ground teams. Hp ice takes out landorus-I and giga drain is used for pokemon such as hippowdon and Seismitoad. AV set also puts in work vs water teams where celesteela can threaten water types with giga drain. Earthquake is used for opposing heatran,Air slash can be used to do good damage to fighting types that threaten the core. .Flamethrower allows celesteela to get past steel types such as ferrothorn.

: Excadrill due to its ground typing provides an important electric immunity to the core.So it can check threats like tapu koko for the core. Excadrill with a choice scarf set deals with fire and flying types such as Mega Charizard Y and Volcarona.Iron head and Earthquake are stab moves,earthquake allows it to deal with rotom-wash since mold breaker ignores levitate. Iron head has a nifty 30 percent chance to flinch and is used vs pokemon that resits its earthquake such as tapu bulu.Rapid spin is used to clear off hazards which may wear down teammates. Toxic can be used to cripple Mega sableye and other walls that like to switch into excadrill.
Threats

: Fighting types like Mega Gallade and Keldeo pose a huge threat to this core since the core is open to fighting moves as it lacks any immunity to it.

: Water types like Mega swampert and Azumarill can break this core as Mega swampert threatens heatran and excadrill and celesteela cannot switch in on Mega swampert in rain. Choice banded azumarill doesa number to this core with aqua jet and waterfall.

: Magnezone is a threat to this core on electric mono teams as it can trap and take out celesteela which is OHKO :
252+ SpA Choice Specs Magnezone Thunderbolt vs. 252 HP / 32 SpD Assault Vest Celesteela in Electric Terrain: 468-552 (117.5 - 138.6%) -- guaranteed OHKO
Magnezone can also trap excadrill locked into rock slide and take it out with specs Hp fire:
252+ SpA Choice Specs Magnezone Hidden Power Fire vs. 0 HP / 0 SpD Excadrill: 306-362 (84.7 - 100.2%) -- 6.3% chance to OHKO
Good Teammates:

: Skarmory is a great teammate for this core since it can provide dual hazards in stealth rock and spikes with a suicide lead set, skarmory's dual hazard is really good if heatran is running stone edge in the last slot. The dual hazard allows for hazard stack which is well appreciated by excadrill and other possible offensive teammates.

: Bisharp is another good teammate since it can function as a wall breaker-cum-Sweeper. With swords dance it breaks down walls and provides utility support with knock off to the core.Bisharp also deteres defog users if skarmory is used with dual hazards.

: Scizor-Mega is a fantastic set up sweeper since its typing allows it to set up vs plethora of types and its weakness is covered by heatran on the core.

:Magnzeone is a decent teammate for the core to check fighting types like keldeo with a choice scarf set, it can also trap and take out annoying walls like ferrothorn or skarmory for offensive teammates, while providing volt switch support to bring in teammates.

Since a core around Mega beedrill is needed, here is one:
Offensive Poison Core

Core

Beedrill-Mega @ Beedrillite
Ability: Adaptability
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- U-turn
- Poison Jab
- Drill Run
- Knock Off /Pursuit

Nidoking (M) @ Life Orb
Ability: Sheer Force
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Stealth Rock
- Earth Power
- Ice Beam
- Flamethrower

Description

Overview:
This is an offensive poison core around Mega beedrill where Nidoking helps to ease off the steel match up where mega beedrill struggles. Mega beedrill and Nidoking is a good core as both the pokemon take out each others checks. Nidoking on the core also provides stealth rock support which is appreciated by mega beedrill to score easy KOs, Mega beedrill on the other hand takes care of psychic types that trouble nidoking while providing U-turn support to bring in nidoking safely.I dont think the sets needs much explanation since the sets are standard so I will skip to good teammates section.
Good teammates:

: Since the core is weak to ground types and ground moves,crobat is a great teammate since it provides a ground immunity thanks to its part flying typing. Crobat also provides defog support to Mega beedrill which is susceptible to hazards.

: Evioltie Golbat can be used as well in place of crobat since it not only provides U-turn and defog support like crobat but eviolite golbat is much bulkier and so it can check threats like Mega Pinsir as well.

: Muk-alola is a must to have since it comprises roles on a poison team such as Psychic type check and a sp.def pivot. Since the above core lacks a switch in to psychic types such as latios,Muk-alola does a good job of dealing with such psychic types while providing knock off support to cripples item reliant pokemon such as chansey or porygon2, something where poison struggles.

: Toxapex is another good teammate since it can check set up sweepers like volcarona,Scizor and bisharp with haze which can prove to be troublesome otherwise. Toxapex can provides toxic spikes support to the core which gradually wears down teams and makes cleaning easier.

:Since Mega Beedrill is used, Mega venusaur cannot be utilized so using Amoongus as a pivot to physical attacks aimed at mega beedrill and nidoking is a good option. Amoongus has spore which is one of its selling point, the ability to cripple a pokemon can be huge in battles, if using toxapex then amoongus forms a great regenerator core with it that can be annoying to break.

Offensive Ice Core

​

Importable

Lapras @ Choice Specs
Ability: Water Absorb
EVs: 80 HP / 252 SpA / 176 Spe
Modest Nature
IVs: 0 Atk
- Hydro Pump
- Surf
- Freeze-Dry
- Hidden Power [Fire]

Mamoswine @ Life Orb / Choice Band
Ability: Thick Fat
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Earthquake
- Icicle Crash
- Ice Shard
- Superpower / Knock Off

Kyurem-Black @ Choice Scarf
Ability: Teravolt
EVs: 252 Atk / 4 SpA / 252 Spe
Naive Nature
- Outrage
- Fusion Bolt
- Iron Head / Earth Power
- Ice Beam

This core features Lapras and Mamoswine as the respective special and physical wallbreakers along with Choice Scarf Kyurem-Black to clean late-game. For Lapras, the 176 EVs in Speed are used to outspeed max Speed Azumarill to make sure it can be KOed by Freeze-Dry. The set itself is pretty standard, as is Mamoswine's. Life Orb can be ran for the versatility, but Choice Band gives you a bigger power increase. Superpower is mainly to hit Heatran and Ferrothorn, but Knock Off can also be nice for removing Chansey and Porygon2's Eviolites, as well as being able to KO Jellicent. For the Kyurem-Black, Iron Head is pretty important for KOing Mega Diancie, but Earth Power is a decent alternative for doing good damage against Heatran and Excadrill.

Good Teammates

Alolan Ninetales can set up Aurora Veil for the core while also being able to cripple things with Encore.

Piloswine can set up Stealth Rock for the core while also being able to consistently switch into Heatran and Nihilego. It additionally does some phazing with Roar.

Avalugg can remove hazards for the core while also switching into Choice Scarf Excadrill, Jirachi, and Infernape. It can also phase things out with Roar.

Threatlist

Scarfed Fighting types give the core a ton of trouble, since Kyurem-Black can't really outspeed either of these threats.

Offensive Mega Scizor variants are easily the most threatening, since they can outspeed and KO Lapras with a +2 Superpower. It's pretty much unavoidable for Ice to have a rough time with this thing.

Offensive Ice Core

​

Importable

Ninetales-Alola @ Light Clay
Ability: Snow Warning
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Aurora Veil
- Freeze-Dry
- Moonblast
- Encore

Sandslash-Alola @ Life Orb
Ability: Slush Rush
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Icicle Crash
- Iron Head
- Earthquake
- Swords Dance / Rapid Spin

Weavile @ Life Orb
Ability: Pressure
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Icicle Crash
- Ice Shard
- Knock Off
- Pursuit / Low Kick

With Fairy and Psychic being the best types in the current metagame, this offensive core is amazing on Ice teams. For Alolan Ninetales, the set is pretty standard, but you can choose to run Icy Rock over Light Clay if you want to give Alolan Sandslash more sweeping turns. However, Aurora Veil does do a nice job of letting it set up safely with Swords Dance. But Rapid Spin can be ran on more HO teams that don't carry Avalugg when you need hazard removal. As for Weavile, Low Kick can be ran over Pursuit if you're looking to hit Heatran and Tyranitar, but Pursuit is really nice for dealing with Victini and Latios, as well as Alolan Marowak to keep it from getting up Stealth Rock later. Overall, the core is meant to do nicely against offense, but will struggle rather heavily against more balanced types.

Good Teammates

Mamoswine is easily the type's best Stealth Rocker, which greatly helps the core with cleaning. It can also serve as a nice blanket check with Focus Sash and Endeavor+Ice Shard.

Kyurem-Black can support the core with its amazing wallbreaking, being able to break through Toxapex, Mega Venusaur, and Skarmory. It also has good enough bulk to switch into some weaker Fire type attacks from Torkoal and Heatran.

Avalugg can serve as a bulkier Rapid Spinner to allow Alolan Sandslash to always run Swords Dance. It can also switch into Scarf Terrakion and Infernape, which severely threaten the core.

Lapras and Walrein help the core by checking Mega Scizor, which is easily one of the biggest threats to any Ice team. Lapras can also check Water types like Belly Drum Azumarill and Toxapex, while Walrein can switch into Fire type attacks quite easily thanks to its great bulk and access to Thick Fat.

Threatlist

Just like with the previous core, Scarfed Fighting types are an extreme pain to deal with, outspeeding everything on the core and KOing with either their Fighting STAB or their respective secondary STABs.

Pretty self-explanatory tbh. Mega Scizor can just set up and tear through the core. Despite Alolan Sandslash taking a Bullet Punch, it can't do anything notable back unless it has a Swords Dance boost, and even then it's unable to KO it.

As you may imagine, bulky Water types are a serious issue for the core. The core just gets stalled out by Vincune, even with Alolan Ninetales's Encore, and Toxapex can be a serious issue between Scald burns and Regen recovery.

Description

With USM, Water teams finally have a decent sticky web setter in Araquanid which allows slow hard hitting Pokemon such as Gyarados Crawdaunt, Keldeo have an easier time versus opposing teams. The core of Mega Swampert / Seismitoad and Araquanid compliments each other well since Mega Swampert or Seismitoad provides stealth Rock support along with an electric immunity and Araquanid provides sticky web support.
Araquanid : Scald is used to fish for burns and to cripple physical mons. Liquidation is also an option as it hits harder and has a nice chance to drop defense stat by one stage. Toxic allows it to cripple opposing walls such as mantine, Porygon2 etc. Mirror coat allows it to deal good damage in return to special attackers like Mega Charizard Y,Latios,Volcarona etc. Magic coat is an option that is better suited on sash lead set to bounce back taunt or hazards from opposing Hazard setters.
Seismitoad: Seismitoad can be used on the core if the team is opting for some other mega evo on the team such as Mega Sharpedo or Mega Gyarados, It is an offensive stealth rock set with life orb boosting the power of its move. Hydro pump and earth power form its STAB move which has decent coverage while sludge wave is used for fairy types.
Mega Swampert: Mega swampert is also a great option along with Araqunid as it can set up Stealth rock and still pose a threat to opposing teams by utilizing Rain dance to be faster, hence keeping up the momentum. Waterfall and Earthquake form its STAB moves while Stealth rock support helps offensive teammates to have easier time vs opposing teams.

Good Teammates

Mega Sharpedo: It is a great teammate if the team is using seismitoad for stealth rock and electric immunity. With webs support sharpedo can use an adamant nature to hit more harder, its ability speed boost also helps the team outside of webs support, amazing cleaner and a check to weakened mega venusaur.
Gyarados: Gyarados is another teammate that greatly benefits from the webs support as it is able to threaten opposing teams after a single dragon dance, which can snowball into a sweep along with its ability moxie, it is also good at breaking defensive poison core which is trouble for water teams otherwise.
Keldeo: With webs support Choice specs keldeo can easily spam its high powered moves vs opposing teams with worrying much about getting outsped by faster threats such as tapu koko. It also helps a lot vs normal teams.
Greninja: Greninja is easily splashable on webs water team as it can utilize life orb set, checking threats like ferrothorn and Mega Venusaur with hp fire and extrasensory respectively.
Some more teammates: Belly drum azuamrill, Crawdaunt, Tentacruel for toxic spikes immunity and Rapid spin support.

It also does a great job vs Dragon-type teams as it is able to threaten with Ice beam. Dark pulse is for Psychic type teams as U-turn and Dark pulse helps to pressure it. U-turn also allows wallbreaker like Keldeo to come in easily and fire off a move. Keldeo on the team deals with normal and steel types, it breaks down wall which makes it easier for Greninja or Gyarados to sweep/clean. Gyarados on the core deals with the Poison match up, checking threats such as Mega Venusaur with Fly z and it is a great Dragon dance sweeper in general. One can run intimidate to easily set up Dragon dance. Moxie is also a good option as it can allow Gyarados hard to check defensively, snowballing into a sweep.

Good Teammates

Swampert: It is a good teammate as the core can rely on it for electric immunity and as a wall to tank hits, it also provides stealth rock support which is well appreciated by the offensive water core.
Toxapex: It provides Grass neutrality to the team and a switch-in to Mega Venusaur and Mega Charizard Y, can provide Toxic spikes support to break down opposing teams.

Little speed investment allows it to outspeed Alolan Marowak, Golem and uninvested speed Scizor enabling it to use foul play first.

Mega Diancie:It's Mixed attacking set makes Mega Diancie a very good mixed wall breaker for the team able to break cores easily such as poison core (Psychic + Diamond storm) with its physical and special moves. It is also the Stealth Rock user of the team to support the team and make match ups such as flying very easy. It has good speed at base 110 which is further complemented by sticky web support.

Lastly Excadrill provides speed control with a Choice Scarf set and acts as a check to Fire and Electric types such as Mega Charizard Y, Volcarona and Tapu Koko. Together this core patches up a lot of match ups for Steel-type teams as they cover each other well.Heatran can run Stone edge on the set over Stealth Rock if the team has other Stealth Rock setter such as Skarmory or Ferothorn, Toxic is also a neat option to wear down walls in tandem with Magma storm + Taunt.

Skarmory: It provides Stealth Rock support so Heatran can run other optional move on the set such as Stone Edge or toxic, it cab be relied on as a physical wall and a check to fighting type providing fighting neutrality and ground immunity to the core. It can also run dedicated suicide lead set to set up both Spikes and Stealth rock for the core.
Celesteela: Celesteela is another teammate that works well with the above core, one can run a defensive set which allows to tank special hits for the team and stall break with leech seed + Protect, AV set can be used on more offensive team along with the core to patch up Ground match up for the team.
Mega Scizor: Very good set up sweeper that has good synergy with Heatran and Excadrill, and appreciates Jirachi covering Water types for it.
Ferrothorn: It is an option if the user wants to build a balance team with the core, its utility set of Spikes and Leech seed compliments well with the core as it wears down opposing team making it easier for offensive teammates to deal with opposing teams.
Bisharp: Another set up sweeper that greatly benefits from the core covering various matchups, Bisharp can run Z move set with swords dance to open up big holes vs opposing teams, it also an asset vs Psychic match up, being able to threaten Psychic-type teams with Knock off + Sucker Punch combo. Works well on both balance and offensive builds with the core.

- Close Combat

- Mach Punch

Description

With a Choice Scarf, Blacephalon becomes a revenge killer and an additional sweeper for Fire teams, letting Infernape take the role of a wallbreaker and priority user. Blacephalon takes on Dragon, Ghost, Ground, Poison and Psychic teams (Psyshock revenge kills Choice Scarf Nihilego from full HP, which Fire teams greatly apreciate) that Infernape struggles with, while Infernape destroys Dark, Normal and Rock teams (in particular, Infernape's Iron Fist-boosted Mach Punch OHKOes Greninja and M-Sharpedo before they can even move) that Blacephalon generally can't do much against. Infernape can also take out Alolan Muk for Blacephalon so that it can efficiently clean Poison teams, and safely bring it onto the field with U-turn.

You can swap each other's role and, consequently, change some moves (when using Specs Blacephalon and Scarf Infernape, it's usually Trick > Psyshock and Earthquake > Mach Punch) and Infernape's ability to Blaze, but the role compressing that Scarf Blacephalon brings to Fire teams is often too good to pass up.

Good teammates

Rotom-H can use its slow Volt Switch to safely bring either one of them onto the field and Defog or its screens to protect them from entry hazards and being KOed by strong opposing moves. It can also switch into Ground-type moves aimed at either Blacephalon or Infernape. Torkoal is pretty much mandatory for any serious Fire team, as it summons the crucial sunny weather (making Fire-type moves stronger and opposing Water-type moves weaker), sets up SR, clears entry hazards away with Rapid Spin and tanks priority moves aimed ateither member of the core. M-ZardX forms a nice sweeping duo with Blacephalon and can clean through opposing teams once Infernape has weakened them with its strong attacks.

Description

With Landorus' Gravity, Dugtrio can trap and remove annoying Flying-types like Celesteela, Zapdos and M-ZardY for Ground teams. Dugtrio can also trap and dispose of some speciall walls like Chansey for Landorus, while it deals with other walls, such as Skarmory and Ferrothorn that Dugtrio can't touch. What's more is that since Scarf Tapu Bulu needs to use Wood Hammer to OHKO Landorus (it survives Horn Leech and Bulu gets KOed by Landorus' Sludge Wave), leading to major recoil for Tapu Bulu, this situation translates into a free switch-in for Dugtrio and an opportunity to successfully trap and remove one of the most dangerous threats for Ground teams. In fact, if Dugtrio's Sash is intact, it can trap and KO a vast multitude of threats that Landorus, and Ground teams in general, hate facing, such as Specs Keldeo, Scarf Greninja locked into Ice Beam and Alolan Raichu in Electric Terrain.

Good teammates

Hippowdon, for its ability to break opposing Focus Sashes with SR and the sandstorm it summons (which enables Landorus to effectively OHKO Breloom), in addition to sponge priority moves aimed at either Landorus or Dugtrio, is a great teammate to this core. Excadrill is actually a necessicity for this core, as its Rapid Spin clears entry hazards its side of the field, ensuring Dugtrio's Focus Sash won't be broken upon its entrance onto the field. The Sand Rush variant, if used with Hippowdon, also becomes a dangerous cleaner once Landorus has punched holes in the enemy team and Dugtrio has removed (or at least weakened) some threats to Excadrill's sweep like M-ZardY and Torkoal. Seismitoad or Gastrodon is always appreciated on any kind of Ground team due to their Water-type immunity, the former having more offensive presence and access to Knock Off, while the latter has the greater longetivity between the two and can repeatedly switch into Keldeo's and Greninja's attacks. Additional wallbreakers like Garchomp, M-Garchomp (if using Gastrodon) and Mamoswine is also appreciated to pressure slower teams even more.

Explanation

Mimikyu is a good cleaner, being able to set Swords Dance safe since he has Disguise. With a powerful Fairy-type stab move, Mimikyu can win Dark and Dragon matches easily just spamming Play Rough. Mimikium Z allows him to kill some bulky walls like Mandibuzz, consequently sweeping the remaining team without problems. Shadow Sneak give him safety against Psychic and Ghost matches, being easier to clean the enemy team. Mimikyu can learn Wood Hammer, winning a water match without problems.

Sableye-Mega is a bulky wall, being able to knock out some important itens like Choice Scarf, making Mimikyu's sweep easier. With Magic Bounce, Sableye can bounce back sticky web and Will-o-Wisp, Toxic and Thunder Wave, preventing Mimikyu from being stalled until death or stopped. Recover is a important recovery move and needed. Will-O-Wisp can drop the attack stat of important mons, like Mega Swampert and Mega Scizor.

Blacephalon is the perfect offensive option. As a Fairy-type, Mimikyu has a lot of problems against Steel-types, being killed by almost all stab steel moves, Blacephalon with his high special attack and a good speed can easily clean all steel types for Mimikyu, making another sweep with Beast Boost or just letting Mimikyu sweep easier. About the moves, Fire Blast and Shadow Ball are his stabs. Psychock is really good against poison-types, Blacephalon can sweep all the enemy team if Alola-Muk/Drapion dies to Mimikyu. Trick is a good option to use against stall mons, like Chansey and Porygon2, removing their eviolite and trapping them in one useless move.

Hey, this core is good but to make it better i would suggest changing a couple of sets. Firstly the Mimikyu set to Mimikium Z or life orb. On a Ghost team you have the necessary ghost attacks and power to not need the ghostium z coverage on mimikyu. Ghostium z doesn't pick up any important KO's that Mimikyu or blacephalon cant manage with their regular ghost type attacks. Life orb/ Mimikium give you more breaking power especially against a type like normal that can wall ghost somewhat easily. Mimikium z can kill off Staraptor and P2 after chip or being knocked by Sableye. and can break Mandibuzz without a boost using Lets Snuggle forever.

Another set worth changing is your Blacephalon. Hp ground isn't really necessary on blacephalon since the majority of Heatran's run air baloon which restricts their recovery. With Shadow ball + rocks as long as you are patient you can break Heatrans after a couple of swichins.
Over this slot you can run Psyshock to help with the poison matchup as psyshock will break through poison if you play around muk alola with your defensive core although easier said than done.
Alternatively a more worthwhile Hidden power worth running would be Ice, this would help with breaking bulkier flying type cores if you play aggresively against mantine by doubling with mimikyu to prevent defog you will be able to kill off the mantine when its low and beast boosting HP ice will allow you to break flying cores easier, dealing a lot of damage to zapdos, landing OHKO's on gliscors and forcing out steela with fire attacks and trick.

This is fairly standard when people think of standard dark with the Defensive core of Mega Sableye (the fighting immunity/mixed wall), Mandibuzz (the ground immunity/spore switchin), and last but not least Tyranitar (the specially defensive wall/rocks setter). These three pokemon are on every standard balanced dark team. Tyranitar and Sableye both have protect allowing them to scout choice locked Pokemon attacks such as Victini and Mandibuzz is capable of checking Physical attackers with Foul Play. Both Tyranitar and Mandibuzz have Toxic, Mandibuzz can toxic stall with roost and Tyranitar can Toxic stall with Protect+sand chip. Overall this Defensive core is super hard to break for most balanced teams and is a solid addition to any dark-type team.

Scarf Greninja+Curse Muk+Taunt/Z-Draco Hydreigon became very popular on Dark-type teams being spammed all through MLT and MPL thanks to this very successful rmt by roman. Muk-Alola uses Gluttony so it can pop its pinch berry at 50% rather than 25% allowing it to fairly easily setup curse alongside recycle and is also any Dark-type teams best chance against Fairy-type teams. Scarf Greninja is really nothing new but still a fantastic addition to this Dark type offensive core, as it can check pokemon such as Landorus with Ice Beam, Tapu Koko and Tapu Bulu with Gunk Shot, Mega Diancie with Hydro Pump, and can take advantage of the fact it forces alot of switches with U-turn. Finally Z-Draco is a fantastic 1 time nuke that when paired with Taunt allows it to being a fearsome fat breaker allowing it to take on the likes of pokemon such as Toxapex.

This Dragon core is fairly common is the USM Metagame and a very effective Offensive Core. Kommo-o gained a powerful new Z move in the USM Metagame that allows it to become a threatening sweeper that omniboosts all its stats by 1 stage. With another Dragon Dance Kommo-o outspeeds the entire unboosted metagame including threats to the core such as Choice Scarf Greninja. It also puts in immense pressure as a lead Pokemon that can just click z-move freely if there are no Fairy-type Pokemon and easily take out 1-2 Pokemon before it gets knocked out. Kyurem-Black is a very classic and still solid addition to any Dragon-type team being able to threaten every Pokemon thanks to its boltbeam coverage and hit annoying steel-type pokemon with Earth Power such as Heatran making it hard to switch into based off pure resistance. Kyurem-Black also shreds through the current fat balance flying and water teams that are being spammed by so many people on ladder and tours. Finally Latios is the revenge killer and emergency defogger allowing it to clear hazards before almost every pokemon thanks to its blistered 525 speed after a choice scarf boost. It is also capable of crippling walls such as Chansey and Porygon2 with Trick which can still be a nuissance to Dragon-type teams if Kommo-o is not in the game.

Ability: Surge Surfer
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Nasty Plot
- Thunderbolt
- Psychic
- Grass Knot

This core is fairly self explanatory with Alolan Raichu + Tapu Koko being a timeless core since the beginning of SM, however with the recent edition of Zeraora in USM Monotype it has given the Electric Monotype a whole fresh new breathe of life. Raichu is carrying these attacks so it can target Ground-type Pokemon such as Hippowdon and easily run through the defensive core of water that relies on Swampert or Seismitoad as its Electric-type immunity. Raichu Alola is also capable of OHKO Muk with its +2 Z-move in electric terrain then leaving it to pretty freely clean through poison-type teams. Zeraora is an amazing Electric-type pokemon that finally makes the normal matchup not so god damn unbarrable, having 0 switchins on Normal-type teams is huge for electric as its Fighting-type moves 2HKO Chansey & Alolan Raichu and can knock out staraptor with its Plasma Fists in terrain even after an attack drop from intimidate. Finally Tapu Koko is an answer to Dragon-type Pokemon leaving all Dragon-type pokemon who can not outspeed and OHKO it suspectible to Specs Dazzling Gleam.

Offensive Fairy Core #1

Tapu Koko @ Magnet
Ability: Electric Surge
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 30 Atk

Tapu Bulu @ Choice Scarf
Ability: Grassy Surge
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Wood Hammer
- Horn Leech
- Stone Edge
- Superpower

This core has existed since SM but for some reason is not in the Good cores section for Fairy-type teams. What is there to explain about the broken tapus, Tapu Koko can fairly easily take on Flying-type teams thanks to Thunderbolt in tandem with HP Ice, while also being able to act as pivot and bringing in a more favorable matchup with U-turn. Tapu Bulu is there as the teams Choice Scarfer and one of the 2 main physical wallbreakers. It can take on Water- and Ground-type Pokemon fairly easily then its coverage in Superpower and Stone Edge allow it to take on pokemon like Heatran and Mega Charizard Y, respectively.

Mimikyu @ Life Orb

Ability: Prankster
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
IVs: 0 Atk
- Light Screen
- Reflect
- Foul Play / Thunder Wave
- Spikes

With Psychic being ever so popular as always and Mega Diancie being able to run Stealth Rock many Fairy-type teams have stopped using Clefable in favor of using Mimikyu. This Pokemon thanks to disguise can easily setup infront of most pokemon however its disguise does not prevent it from getting statused. SD in combination with Shadow Claw and Shadow Sneak can fairly easily run through Ghost- and Psychic-type teams, while Play Rough lets it take on pokemon such as Mega Sableye and Keldeo. Mega Diancie is the poison-type killer with Diamond Storm+Psychic being able to 2HKO all viable Poison-type Pokemon makes it a large threat and Moonblast/Stealth Rock are fairly self explanatory. Klefki is the teams spike stacker and screens setter, it also Mimikyu to setup with far more ease while also granting an immunity to Poison-type attacks. Klefki can also check Pokemon like Mega Scizor with the likes of Foul Play or cripple fast pokemon such as Mega Aerodactyl with Thunder Wave.

Offensive Fighting Core

Kommo-o @ Kommonium Z

Naive Nature
- Clanging Scales

Cobalion @ Life Orb
Ability: Justified
EVs: 4 Atk / 252 SpA / 252 Spe
Naive Nature
- Hidden Power [Ice]
- Focus Blast
- Stealth Rock
- Stone Edge

This core is a very good example of what Fighting teams look like in USM, with the introduction of Kommoium Z Fighting got a small and albeit not very large bump in viability but still nonetheless a somewhat better stance in the metagame. Kommomium-Z + Taunt breaks down Balanced cores because it prevents it from being status such as Toxic from Zapdos and or being Hazed by Mantine. Flamethrower + CC form a steelbreaking core of attacks and each have the individual uses like being able to hit Ferrothorn and Heatran, respectively. Finally Offensive SR Cobalion is a nuissance to Flying-type teams as it threatens the Defoggers with HP Ice and Stone Edge, allowing it to pick up large amounts of surprise chip against Pokemon like Gliscor. This core was directly taken from a post made by Wanka in the creative/underrated sets thread but I thought it was also worth sharing here.

Jolly Nature
- Stone Edge
- Earthquake
- Pursuit
- Stealth Rock

With Pokemon like Toxapex and Mantine being introduced and popularized in Gen7, respectively the old powerhouse Mega Charizard Y is falling out of favor and more Balanced cores with these pokemon are becoming more and more popular and for good reason. Mega Aerodactyl provides invaluable role compression for Flying-type teams being a fantastic rocks setter, having a fantastic speed tier allowing it to outspeed the likes of Tapu Koko and Mega Lopunny, and being able to Pursuit trap threats to Balanced Flying like Victini especially after a V-create drop make it a very solid pokemon for Balanced Flying-type teams. Tornadus-T forms the hazard/removal core with Aerodactyl being able to Defog away Stealth Rock while also being able to nuke Pokemon like Mega Venusaur with Supersonic Skystrike, which this archetype of Flying has trouble breaking through. Finally the annoying ass wall that everyone hates, Celesteela. With access to Leech Seed, Protect, and Toxic it very easily can chip down tons of Pokemon and gain back health at this same time. Heavy Slam allows it to hit annoying Ice-type Pokemon which it also happens to have a resistance against.

Relaxed Nature
IVs: 0 Atk / 30 SpA / 0 Spe
- Transform

With the rise in usage of Pokemon such as Baneful Bunker on Toxapex in favor of scouting Choice Locked pokemon such as Diggersby, it has a new set that disturbs Balanced Water and Poison cores that rely on Baneful Pex as the scout for Diggersby. It quite simply sets up an SD infront of Toxapex as it either switches or clicks Baneful Bunker to scout Diggersby attack. This then allows Diggersby to take on all Water-type Pokemon bar Keldeo and Suicune after Stealth Rock chips. Mega Lopunny's quite standard Encore+PUP has that option which preys on walls to use recovery moves to lock them into encore than proceed to boost Lopunny's attack with power up punch. Lopunny can also run Substitute+Encore/Ice Punch, both of these sets have their different uses and allows Lopunny to become somewhat hard to tell exactly what it is going to do until it reveals a few moves. Ditto is self explanatory, copy setup sweepers and then proceed to sweep.

Crobat @ Black Sludge
Ability: Infiltrator
EVs: 228 HP / 148 Def / 132 Spe
Jolly Nature
- Brave Bird
- Taunt
- Defog
- Roost

This is a fairly nice Balanced Poison-type core that can make the Steel- and Bulky Water-type matchup a lot less tedious and quick. Thanks to SubToxic Salazzle with Corrosion it is possible to Poison pokemon such as Ferrothorn and Toxapex which otherwise pose to be quite a nuisance to Poison-type teams and can take out the former with Flamethrower. Substitute+Protect allow it to Toxic stall Pokemon out easier and the latter can also be used to scout choice locked Pokemon such as Infernape's attack. Mega Venusaur provides Leech Seed support making the ever so annoying Salazzle even more impossible to take out. Finally Crobat is the Defogger and provides a much needed Ground-type immunity for Salazzle. Honorable mentions for teammates are Alolan Muk for the Specially Defensive wall and added Psychic attack immunity, Nidoking can provide Stealth Rock support and is an Electric-type immunity and Toxapex is just an annoying ass wall that sets up tspikes and clicks recover, lmao.

[Hyper+space12]

Balanced Dragon Core:

I noticed that this thread has not experienced any new posts in a really long time.
If I shouldn't be posting on this dead thread I'm completely ok with it getting deleted.

Mega Altaria:
Altaria mega is the dragon immunity of the team when needed to pivot from dragon type moves. It can also super effectively hit other dragon types with STAB pixilate return. Altaria also helps kyurem-black by resisting the fighting moves its weak to.

Garchomp:
Garchomp resists the poison type that threatens altaria out to switch, and can hit steel and poison types that threaten the other two pokemon, while setting rocks that weaken the enemy so it is easier to wallbreak, and rocks are also good for chunking ice types.

Kyurem Black:
Kyurem black resists the ice type that can push garchomp and mega altaria out, and fusion bolt hits flying types that are immune to garchomp's earthquake.

welp i know it was a really short overview but I hope it suffices.
