Serebii Suspect Discussion

This thread is here for members of the Serebii community to discuss either current Pokemon being suspect tested by Smogon or Pokemon that you or others may feel deserved to be tested. This is NOT a thread to just spam with "Ban suchandsuch because its too strong" or "it sweeps my team." We need meaningful discussion backed with relevant information. This means for every post in which you either agree or disagree with a certain Pokemon being mentioned you need to back your opinion with information to support your argument.

Claiming a Pokemon does not perform well in Ubers, therefore should not be banned is NOT an acceptable argument, as a Pokemons performance in Ubers has no merit on its being banished to there or not.

Now for specific Pokemon Discussion!
