Papi/Manny said:First off, yay. Somebody who can spell Manny right. Anyways, wasting two bench spaces is absolutely horrible to stop one pokemon while not even developing your side (unless you're very lucky). It dies in two hits and a good GaG player (which is the only GaG player you really need to worry about) can easily counter mawile. So its not worth the wasted resources running it/playing it and using it.
I still think it is a pretty good counter to G&G but I see your point.
