Let me break down some key points...
Scarf Koko with Discharge outspeeds Mega Sceptile and gives it a special attack boost before it attacks, and heals Thundurus thanks to Volt Absorb.
Double taunt (Tornadus/Thundurus) completely shuts down trick room and tailwind attempts, and also gets past mental herb Cresselia/Mimikyu as I'll double taunt it.
Snorlax is there as a nuke, barely anything lives banded double edge. Also there if somehow trick room goes up.
Prankster rain dance shuts down weather from Charizard Y/Tyranitar and allows the genies to live flare blitz from Incineroar comfortably.
Sludge Bomb on Thundurus catches Bulu off guard every time.
Teams that counter mine:
Murkrow. Can't taunt dark types with prankster Tornadus, Thundurus can't taunt quick enough. Tailwind almost guaranteed unless I lead Incineroar/Thundurus and I don't get faked out.
Rain teams.
