I made a new team with a focus on sweeping done by the likes of Garchomp (My fave), Volcorona, and Urshifu with some support through Pokemon's like Ferrathorn, Mandibuzz, and Blissey. Changes and Criticisms are welcome!
Diablos (Garchomp) @ Leftovers
Ability: Rough Skin
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Earthquake
- Iron Head
- Scale Shot
Went with Leftovers instead of Life Orb to give Gaqrchomp a slight bulk. Sword Dance and scale shot is like having a Garchomp with Dragon Dance (With the caveat of losing a defense) and the addition of moves like Earthquake and Iron Head could prove devastating upon a prediction.
THorny (Ferrothorn) @ Leftovers
Ability: Iron Barbs
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Leech Seed
- Power Whip
- Stealth Rock
- Spikes
Went with another Field Hazard instead of Knock Off or Gyro Ball to help support the big three of the team. Went with more Special Defense so that Ferrathorn can be more well-rounded and leech seed for sustain and crippling Pokes who stay in by a tad.
Mothra (Volcarona) @ Heavy-Duty Boots
Ability: Flame Body
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Quiver Dance
- Flamethrower
- Giga Drain
- Bug Buzz
The Special Attack Sweeper where one Quiver Dance can wipe out most pokemon who aren't ready for it. Went with Flamethrower instead of Fire Blast or Fiery Dance due to it's good damage and accurate hit chance. Does struggle a lot against Heatran though....
Jojo (Urshifu-Rapid-Strike) @ Choice Band
Ability: Unseen Fist
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Surging Strikes
- Close Combat
- Aqua Jet
- U-turn
Choice Banded glass canon that hits like a truck. Surging Strike for the good good crit damage (is screwed by the Likes of Ferrathorn and Garchomp with rough skin), aqua jet for priority, and U-turn to get out of unfavorable matchups.
Buzzkill (Mandibuzz) (F) @ Heavy-Duty Boots
Ability: Overcoat
EVs: 248 HP / 60 Def / 144 SpD / 56 Spe
Impish Nature
- Roost
- Defog
- Foul Play
- U-turn
Defogger with decent bulk capable to take most hits. Could see this one getting switched out with something else, preferably with a fast Rapid Spinner to get rid of hazards to keep the sweepers healthy and ready to sweep while maintaining the entry hazards on the enemy side.
Bad Egg (Blissey) (F) @ Leftovers
Ability: Natural Cure
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
IVs: 0 Atk
- Soft-Boiled
- Seismic Toss
- Toxic
- Aromatherapy
My stall pokemon whose capable of taking hits from Special Ataccking Pokemon even after a calm mind or quiver dance. Went with Aromatherapy at the end instead of Teleport, in case one of my Pokemon gets hit by a status condition like Burn or Paralysis.

is not really needed if you already have a Blissey 
and Mandibuzz 
main advantage over Corviknight 
is to handle Dragapult 
, but you already have one of the better check to Specs Dragapult in the whole tier. I think that, changing a bit the defensive core to deal with most SS OU big threats may greatly improve this team, as there are already some good ideas here.
and has a hard time to check things like Kartana 
and Dragapult 
: Ferrothorn is a Water resist, but can’t deal with Urshifu-R 
and even if stack hazards is useful, Ferrothorn won’t bring much utility here. You rather have an efficient bulky Water type like Toxapex 
. Shed Shell could be an interesting item to avoid being trapped by Heatran :heatran; or Whirlpool Tapu Fini.
-> 
able to pressure your defensive backbone. Dragapult 
. This is the classic Choice Specs set:
, Earthquake has 150 base power while Iron Head have 160, so not a big difference.
