i know "How would I counter Charizard Y?" is already there, but I am asking for a counter for his common switches, like Rotom-Wash. it is so annoying when you could kill a really strong Pokemon, and then they switch out for a counter which takes little to no damage from your move. so I want a Pokemon that forces Charizard to switch, only to land a super-effective hit on his switch choice. It can be banded, choiced, I don't care, as long as it works. I will even use a set-up if I have to, just help me please.
i forgot to add, please can it kill of charizard as well.
