Realize there hasn't been a post in a minute but damn I really feel like Combusken is still as bad as it was in ORAS. There are no solid checks to it and anything that is switching in probably can't take more than 3 hits. It destroys the normal special walls and anything that resist fighting is gonna die to a fire-type attack. The only mon I can think of that can reliably switch in is Lampent. But with it being weak to rocks and also getting walled out super hard by things like P2 it easily finds itself worn down quickly. I feel like Electabuzz and Kadabra are similar issues but are tiny compared to the issue that is Combusken.
