Wasn't saying that it was a counter. Was just saying that it could learn it. Plus, I do know about STAB and weakness/resistance modifiers.
I think I wasn't clear with my last post. Was hoping that throh could counter. It is 3HKOed with choice band, and 252 attack, using return and throh with 252 def and hp (but that is rarely used)
If he doesn't counter with 252 HP and 252 attack or 252 HP and 252 sp.d then he is not a counter.. (since no one will use 252 HP 252 defense spread).
