Toxicroak???

Keep stone edge to keep the birds away! Very nice moveset, takes care of a lot of types and uses the high attack stat of Toxicroak. Sucker Punch could be a nice trick instead of Earthquake (fighting takes out steel and rock while poison is nothing to be frightened of) to take out Psycho-types or other pokemon with super-effective moves (which obviously you'll know about with anticipation). Very nice moveset nonetheless
