I'm certain there are better sets, but something like this could work fine. Speed is to creep Corviknight and bulky Breloom. I don't think its the best set, I'd rather use this one, but its more defensive.

Highly prefer Earth Power over Hex for Garganacl, but Hex is standard. I've seen Shadow Ball too but Hex seems better.
