[TheCman07]

So yeah, here's my team. charizard y is my wallbreaker, hitmonlee is a revenge killer and spinner, weavile is a pursuit trapper and to get rid of dragons. Serperior is a fast sweeper that can tank a hit or two. Wash rotom is a nice physical wall that can burn threats like mega gallade, lopunny, scizor etc and can act as a pivot. rhyperior is to set up rocks, tank hits and to check talonflame. Please tell me what you think, it would be much appreciated.
