A mixed Bidoof with pretty good coverage. Bidoof has a pretty poor physical movepool, so I just figured why not abuse Simple with Work Up?
Bidoof @ Eviolite
EVs: 236 Atk / 236 SAtk / 36 Def
- Work Up
- Shadow Ball
EVs and Nature give him 14 in each attack stat, perfect to be boosted. Work Up turns Bidoof into a killer by boosting both attacking stats by 2 stages. Return is a nice powerful STAB move. Superpower seems very fitting for Bidoof, and covers the Rock and Steel types Return can't hit. The attack drop is not minded because of the boosts. Shadow Ball covers Ghost types who are immune to it's two other attacking moves.
