Hey! Former OU player here. I migrated to UU because IMO there is way too much going on over there right now. This was my first attempt at an SS UU team, and I feel like it does pretty well. It deals very well with most of the biggest threats in UU right now, and the few losing match-ups I have seen are still pretty winnable, while its even and winning matchups feel almost easy. It does have a problem with some setup sweepers such as Suicune, which requires uncomfortable switches and sac's, as well as Scarf Tini, which usually just ends up being trading until the opponent runs out of switches.
The team is pretty well balanced, no major weaknesses, common Rock types like Nihilego are hard checked by Cobalion. The team is a bit weak to Fire, but as long as Rotom is kept healthy, it is pretty manageable. Now, for the team:
Rotom-Wash @ Leftovers
Ability: Levitate
EVs: 252 HP / 40 SpD / 216 Spe
Timid Nature
- Volt Switch
- Hydro Pump
- Pain Split
- Defog
The main defogger of the team, here to counter the likes of Hippo and Tini. It can outspeed Gyarados with no DD, and the SpD invest is there because the team was having a hard time taking on SpA sweepers. Just the standard defensive pivot, takes hits well, can hit hard, and helps keep momentum. Also, walls most hazard mons, which makes it's defog utility infinitely better. All around great mon that checks a lot of the current meta.
Hydreigon @ Choice Scarf
Ability: Levitate
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Draco Meteor
- Fire Blast
- Dark Pulse
- U-turn
Hydreigon does a great job as speed control, and was originally added to take down Aegislash. If there aren't any huge threats, I usually lead with it, as worst case, you can U-turn out. Has great resists, and can OHKO basically anything that it hits super effectively. I was thinking about going Modest for extra damage, but we would then lose to other Hydreigons, which would probably not be great.
Thundurus-Therian @ Life Orb
Ability: Volt Absorb
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Nasty Plot
- Thunderbolt
- Sludge Bomb
- Focus Blast
Main special sweeper, destroys Flying and Water types like Celesteela, Azu, and Rotom-W. You can switch it in on Electric moves and most of the time, get a free Nasty Plot up. At +2 SpA, STAB Tbolt can deal serious damage to everything except Ground types. There are very few things that fully wall it, the main one being Hippo, which Rotom destroys. Once you take out the stuff that outspeeds it, it often can just come in and clean up.
Cobalion @ Expert Belt
Ability: Justified
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Iron Head
- Close Combat
- Stealth Rock
Originally was Life Orb SD sweeper, I gave it Rocks and Expert Belt, as it almost never got to sweep. Checks Rock types like Nihilego, and STAB Expert Belt CC threatens most things out, allowing for free Rocks. I think another item might be better, but I might need some help on what to use instead. Also likes coming in on Lele and Hatt, and STAB Iron Head forces switches. Very much so rounds out the team's weaknesses.
Amoonguss @ Rocky Helmet
Ability: Regenerator
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
IVs: 0 Atk
- Spore
- Giga Drain
- Sludge Bomb
- Synthesis
The physical wall of the team. Hard walls Zeraora, Krookodile, and Bulu, and Spore can cripple threats. Sludge bomb does respectable damage and has a decent poison chance. Regenerator allows it to take big hits and get out for free. If you know a Knock Off is coming either Amoonguss or Cobalion comes out 100% of the time. If Bulu is running Zen Headbutt, Amoonguss takes about 40%, and can OHKO with Sludge Bomb.
Marowak-Alola @ Thick Club
Ability: Rock Head
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Flare Blitz
- Poltergeist
- Earthquake
- Shadow Bone
Hits like a truck, that's really all that needs to be said. Can take an attack or two from the likes of Lele and Hatt, and force them to switch. All of its attacks will do a meaty chunk to any switch in. I chose to run Rock Head for the free Flare Blitz, since Thundo has Volt Absorb, but you can run either or. You won't be switching it in as much as the rest of the team, but when you do, it will put in work. In general, it is great at revenge killing, as long as the opposing mon can't hit you too super effectively.
So yeah, that's the team. I don't think there are too many glaring weaknesses. If I were to ask for help on anything, I would ask for what item to use on Cobalion over Expert Belt. Hope you enjoy playing it as much as I did.
