S Rank
The best mons in the tier. You can't go wrong with using them to the point where its harder to justify NOT having them on teams.
S

Very stupid mon that can tear up a lot of the meta with its great stab and coverage moves. It is the best win-con with Swords Dance, best wallbreaker with Choice Band, best revenge killer with Bullet Punch. Its simply too good in the current metagame and its impact is so warping on the teambuilder that you are forced to slot a bulky check to it or you simply get overwhelmed. That being said; its also great at keeping other broken threats at bay, such as Alakazam, Terrakion, or Altaria-Mega. So its sort of a mon you need to have on your team almost. If not, then being able to compensate for the lack of it.
A Rank
Metagame staples. They require minimal support to function well and are very good at what they do.
A+

Nasty Plot is an obscenely strong win-con since it packs great coverage for the entire metagame. Its frailty is negligable because of how hard it hits.

Incredibly strong physical wall with a great typing for the meta. Access to Teleport and Regenerator makes it a great slow pivot for Bulky Offense and Balance teams.

This mon can do a LOT. Defensive Rocker, Offensive Rocker, Assault Vest wall, Choice Band wallbreaker, or Dragon Dance sweeper. Access to great coverage lets it lure a whole bunch of mons like Scizor and eliminate them, or just simply remove them with Pursuit.

Has a great typing that gives it a whole bunch of great resistances. Has coverage to deal with annoying steel types like Scizor and Cobalion, and a very solid offensive mon. Dragon Dance sets can get really stupid if Scizor is dead since its incredibly difficult to defensively check.

Great defensive typing and an impressive mixed wall. Spore and Regenerator is great to check some scary mons like Nihilego, Altaria-Mega, Scizor, and some Keldeo Variants.

Choice Band and Swords Dance sets are absurd with Tera since you can just hit incredibly hard or use a defensive tera to setup easily.

Dual Water/Fighting STABs make this an incredibly threatening mon to deal with. It's checks are fairly limited and can more often than not be abused by a different Keldeo variant like Sub Calm Mind.

A great glue mon and a quality check to a lot of threats like the Slowtwins, Keldeo, Sandy Shocks, Meowscarada, or Gastrodon. It partners well with a lot of mons who appreciate its typing and terrain support. It can also be a good wallbreaker with Swords Dance.

Thanks to its high speed tier and access to Protean, this mon is capable of being an offensive check to a ton of crazy threats like Alakazam, Tyranitar, Altaria-Mega, Terrakion, and Keldeo to name a few. It is also the best Choice Scarf user in the tier.

This mon is by far the best Spiker in the tier, using its great offensive profile to force out a ton of scary threats like Tyranitar, Scizor, Terrakion, Keldeo, Nhilego, Gengar, etc. Tera Ice or Grass lets it further expand the amount of mons it can check. Its also great speed control with Choice Scarf.
A

Uses its massive power to easily punch holes into defensive structures. It can also be an incredibly dangerous win-con with Swords Dance and Trailblaze.

Nasty Plot turns this mon into a really scary mon that's only realistically checked by Tyranitar.

Amazing defensive hazard setter with a great typing and ability to be a key check to the metagames scariest mons, such as Keldeo, Tyranitar, Scizor, etc.

An excellent defensive Rocker that can check a ton thanks to its great bulk and typing. I've also seen experimenation with Curse sets, which can be scary with Tera.

Moltres and Latias leaving the tier, diversified the defog metagame a bit. Mandibuzz's great defensive profile and solid utility makes it a fine defensive pivot, switching into a ton of threats without risking a lot.


Both of them are really stupid with Nasty Plot since they pack coverage to hit the entire metagame for big damage, both are good offensive pivots and win-cons. They're pretty much interchangable on teams as well.

The utility that Moltres provided was so good that we've started using copycats. This mon is a great replacement to Moltres and does it job as a Scizor check and Defogger pretty well.

Offensive Rocker sets are good, but Meteor Beam is a fantastic win-con. Even more with Tera since Tera Grass with Grass Knot lets you break through standard checks like Slowking, Tyranitar, and Gastrodon.

Nothing can really switch into a Specs Gengar unless you're Muk-Alola or something. Other sets like Nasty Plot are equally ridiculous. I imagine that stuff like SubStatus is also a nightmare to face. If you think its a healthy mon in this metagame, you're severely misinformed.
A-

Good wallbreaker thanks to its 100% accurate Hurricanes.

A great natural speed control option and is a solid cleaner and win-con with Dragon Dance or Hone Claws.

Slowbro, except it can actually check Alazakam, and Keldeo. I think it can revive Snow teams with Chilly Reception, but I'm on the fence about that.

Mon continues to be an impressive cleaner and works well with Hazard Stack teams.

Offers a certain type of role compression that Talonflame doesn't provide, using its additional Electric STAB to pressure Water types easier. This makes its defensive sets a bit more consistent, but its Nasty Plot sets become very scary.

Mon can be broken clicker sometimes. The current defoggers (bar Rotom-Heat and Volcanion) are abused often by this mon, which can be very difficult to answer if it has a free turn to setup Swords Dance or has Defiant triggered. This in addition to its newfound bulk with Eviolite and access to absurd strength with Tera Dark.

Solid offensive typing that soft checks big threats such as Scizor, Tyranitar, Altaria-Mega, Tapu Bulu, Nihilego, etc. This makes it's job as an offensive utility mon better since it can often capitalize off the switches it forces.

Great offensive Defogger that uses its dual Water/Fire stab to pressure every rocker not called Gastodon (even then it can just lure it with HP Grass).

Nice fast pivot that can also act as a win-con with Bulk Up. The pure electric typing gives it a key resistance against Scizor and sports solid coverage to check threats like Terrakion or Tyranitar.

great defensive typing and good special bulk to handle a plethora of threats such as Alakazam, Nihilego, Tapu Bulu, Meowscarada, and some Tyranitar and Mega-Altaria variants.
B Rank
Solid mons, but they require proper support to function well.
B+

Mon is just unwallable but that's pretty standard for Nidoking. The real kicker is that Tera lets it boost that power to absurd levels either by boosting its STABs even further, or giving it an extra STAB to one of its boosting moves.

The answers to Belly Drum are incredibly limited with Tera since it hits absurdly hard at +6. If it sets up, then you're forced to sack something in order to bring in the actual check. Choice Band sets are no saint either. Just 2HKOs or outright OHKOs everything.

Good fat Rocker that's not passive. Filter also goes a long way since it can eat hits it realistically shouldn't, like a Banded Close Combat from Terrakion.

Cosmic Power with Tera is incredibly dumb and borderline impossible to consistently check without a Regenerator core.

good Wallbreaker thanks to its Dual STABs and acsess to Knock Off for Slowbro.

Similar to Deoxys but even stupider because it has access to Stored Power and coverage for darks.

Another stupid mon thanks to Tera. Either click Tera Normal Facade to demolish the entire metagame, or Tera Fighting to demolish the entire metagame (its unwallable).

Choice Scarf is really good speed control thanks to it being able to outpace most setup sweepers and the entire unscarfed metagame.

Choice Specs and Calm sets are stupid, especially with Tera, letting it mercilessly tear apart teams without a Water immune or setup incredibly easy.

Meteor Beam and Dragon Dance sets are very strong into a lot of the metagame.

Having two Sand setters in the metagame lets it fit on even more teams.

Choice Specs and Choice Scarf are both really good sets thanks to its great coverage. Other sets like Heavy Duty Boots pivot and Booster Energy are also good sets.

Dark/Fighting coverage is very strong and its access to both Sucker Punch and Pursuit lets it check a ton of threats from Tyranitar to Alakazam.
B

Good into a lot of mons like Alakazam, Nihilego, Slowtwins, Gengar, and Necrozma

Whole lot of broken clickers left in this tier for Ditto to take advantage of. You realistically don't see this on a lot of teams though.

Cool fast pivot that can act as a Defogger, but that's about all it can be right now.

Calm Mind win-con with Pressure. Defensive Tera makes this mon really stupid.

Its a defensive Ground type that isn't a complete momentum sink thanks to Flip Turn

Mega Pidgeot that's reliant on Tera to be good. But it hits like a truck.

SD sets are very powerful but this really slow for that. Choice Band sets hitting a lot of the meta for big damage is great however.

Good offensive rocker and Choice Scarf user in a pinch. Intimidate is nice to withstand some dangerous threats like Tyranitar.

Nice fast pivot and a solid specs wallbreaker on Hazard Stack builds.

Choice Band sets are hella scary to switch into with Tera in the picture. Really fast and gets a strong priority move in Tera Normal Extreme Speed so its tricky to offensively check. Meanwhile Tera Ground is equally threatening since it lets it put massive dents into standard checks like Slowbro and Tapu Bulu.

Heracross, but it got U-Turn (I don't have a lot of experience with this mon).
B-

Calm Mind sets work on occasion, can either bluff by running base Slowbro or just make yourself known with Slowbro-Galar. Both work.

Needs some support but basically just click Shell Smash and cheese your checks with w/e tera of choice.

Has a cool offensive profile for the metagame right now. Can check a lot with its high speed and powerful STABs

Choice Band sets go hard with Tera Fighting, you basically bullshit through your 3 biggest checks in Tapu Bulu, Slowbro, and Amoonguss by using brute force.

^This but just different checks. Mixed sets are also really potent.

Cool offensive rocker that uses Solid Rock to eats hits easier than Tyranitar. It's Ground stab also makes it a scary mon to switch into.

HO mon that has a decent move pool to cover the entire metagame. Very self explanatory mon, but Tera Water or Ground also makes it fairly strong in addition to the usual Z-Crystal sets.

Reuniclus is a fairly solid win-con with Calm Mind sets, pushed even further thanks to tera letting it bypass its offensive checks.

Ghost breakers with Tera are super busted, Chandy wishes it was faster and had an easier way to break Tyranitar however.

Basically if Mienshao and Zeraora fused, then somehow got access to a broken cheese move and a way to heal itself of burns (Natural Cure).
C Rank
Very niche Pokémon that either require a large amount of support, can only fit on certain playstyles, and/or difficult to justify outside of specific cases.
I'm only gonna explain the niche playstyles instead of the individual mons
C+



PsySpam got used a lot during kickoff, with both Alakazam and Armarouge making it a far more consistent playstyle overall. PsySpam cores are more than capable of overpowering the opposition with brute force, or just use Sash spam to setup on everything.
C



Trick Room works sometimes but its pretty much matchup fishing since sometimes a team has the tools to deal with it or not.



No Heat Rock is very bad but Sun teams are still usable to an extent. Although with both Tyranitar and Hippowdon in the metagame, its very hard to get going.



Stall is another playstyle that's basically matchup fishing since it struggles to account for all of the absurd threats running around. Its probably only good if you're counter teaming someone in a tour. I'd prob give this more respect if something like Blissey or Tangrowth dropped, but it's doubtful at this point.
