What would be a good counter to one of these that knows Thunderbolt? I have a friend that's put together a new team after I wiped it with my Mawile, and wants to battle me after I finish retooling my own, and I want to surprise him by knocking it the fuck out as quickly as possible. From the was he's talked about it, his team mostly relies on this and a Charizard, so if I knock it out fast his whole team should fall apart pretty easily.

As it stands, my team is Mawile, Absol, Goodra (currently Goomy), Torkoal, Tentacruel (currently Cool), and Gyarados (Magikarp). The last two I'm on the fence about, however.
