What would it be? I'd go with poison, now that there are ways around thier major weaknesses(psyhic, and steel) they're not that bad.
Skuntank is part dark for psychics and can learn flamethrower for those pesky steel types.
Toxicroak has fighting for steels.
Drapion is like Skuntank, and can use bug.
Roserade for Water, and ground.
Gengar for ground, and some psychic.
Crobat for speed, and X-scizzor.
Maybe Nidoking, Tentacruel, or seviper for others.
Maybe Normal for few weaknesses
Porygon-Z for high specialatk ( give him HB, a normal type boosting item, download, plus his normal type boost makes normal attacks 1 hit KOs)
Ursaring for power
Girafarig for fighting weakness
Snorlax for power and endurance
Slaking for awesome stats
and Zangoose, he's badass and has good stats and moves
