Azuril is kind of like Deoxys-N - overshadowed and thus unused because Deoxys-A (and Marill) are so much better, but still probably broken regardless.
So, how about just banning Huge Power then?
Suddenly, Meditite.
Meditite isn't really a problem, its actually relatively slow and doesn't have very great defenses. It also doesn't get STAB on its priority move, and said priority move is a bad attacking type.
Since it is so bulky, even without Eviolite, and has great Speed, do you think Solar Power is worth considering, too? It can obliterate teams with Life Orb giving it flexibility and recovery if it chooses Giga Drain over SolarBeam.
