Honestly, this set annoys me. You're splitting your EV's between Atk and SpA, which means low powered moves overall, you're dropping your SpD for Spe, which is a questionable choice, and work up just hurts my sensibilities. If you put all your attacks into one category, you could be using Nasty plot, or even Swords Dance--which raise SpA and Atk by two stages respectively, rather than having both boosted by 1, which is less efficient. Furthermore, you are not utilizing STABs--same type attack bonuses which increase power by a full 1.5x when using a move of the same type--which lowers the damage potential substantially.
