mega drain in Pokemon is a grass type move that works better leech seed or leech life
the only thing i would recommend is that you forget mega drain for giga drain at lvl 41 other than that its a pretty good combination
Xerneas does not have a Mega Evolution.
Some of the best types are Fire, grass and rock. For your starter pokemon you should use a Snivy or a Tepig. Snivy's can learn good moves like mega drain but I'm not sure about Giga drain. Tepig evolves into Pignite which is also a fighting type.
Mewtwo can Mega Evolve into either Mega Mewtwo Y or Mega Mewtwo X.
