Bro, you play Gen V UU, right? I've got the perfect idea for a core, but I can't use it cause I'm banned.
SubSplit Chandelure + Toxic Spikes Roserade + ResTalk/Substitute Machamp + Rapid Spin Blastoise.
Chandelure and Roserade set up on Chansey with no issue at all, other than maybe the odd Thunder Wave hitting Chandelure. ResTalk Machamp wouldn't give a shit if Porygon2 hit it with Toxic on the switch, can Rest off damage from Snorlax, remove status, status absorber, etc. On the other hand, SubChamp can switch in Chansey or Porygon2 with some correct prediction, and get a free Sub. Slowbro can't break the core because Roserade + Toxic Spikes, Dusclops gets mauled by Chandelure. Blastoise removes Spikes and Stealth Rock while making sure shit like Froslass can't screw you over.
I'm telling you, man, I think this core could break shit wide open. You've gotta try it.
