Is there anything I can do to improve this team for Super
Rotation battles in the Battle Maison?
-Talonflame w/Lum Berry
Nature: Adamant
Ability: Gale Wings
EVs: 40 HP, 252 Attack, 212 Speed
Moves: Tailwind, Brave Bird, Flare Blitz, Roost
-Rampardos w/Choice Band
Nature: Adamant
Ability: Mold Breaker
EVs: 252 Attack, 252 Speed, 4 HP
Moves: Head Smash, Earthquake, Zen Headbutt, filler
-Gastrodon w/Leftovers
Nature: Relaxed
Ability: Storm Drain
EVs: 252 HP, 252 Defense, 4 Sp.Defense
Moves: Scald, Earthquake, Toxic, Recover
-Hydreigon w/Life Orb
Nature: Hasty
Ability: Levitate
EVs: 252 Sp.Attack, 252 Speed, 4 Sp.Defense
Moves: Dragon Pulse, Fire Blast, Dark Pulse, Flash Cannon
The basic idea is to lead with Talonflame, use Tailwind, then rotate in Rampardos and Head Smash 2 or maybe 3 pokes into oblivion.
It looks good, but you might get wrecked by a bulky ground type. Personally, I'd replace the Scald on Gastrodon with Surf for more power against a ground type that might interrupt your strategy. IMO hitting it hard takes priority over potentially inflicting a burn. Other than that it looks good.
