Suspect testing won't happen in the pre-PokeBank metagame and this is not the place to talk about a potential suspect test of Mega Kanga for the PokeBank metagame. If it is indeed suspect-worthy and when the time is right, the appropriate thread to discuss about its banning will be made.alexwolf, while I do agree that Rocky Helm is a great deterrent for Kangs, I wouldn't say that in itself is enough to completely rule out, in the very least, a suspect test. Arguments presented in this thread are strong enough to support a suspect test at the very least for Kangs, and we shouldn't be so quick to rule out possible banning either.
Luigi player isn't Whismicott a bit unorthodox to consider as a counter / check? What other merits does it bring apart from being Kang, really?
