Gengarite - BAN
Magnet Pull - DO NOT BAN
Reason:
Gengar-Mega is in itself an very difficult Pokemon to counter, but beeing able to fully Trap nearly anyone without counterplay at all, makes him a huge threat.
Magnet Pull on the other Hand only applys to Stell Type Pokemons and while Bh is full of them it is counterable and much less of a problem then Gengarite.
