In my deck I currently have 2 Cobalion EX, 3 dialga EX, 1 Aegislash EX, 1 heatran, and 1 baby cobalion with a 3-3 bronzong line. I have 2 skarmory EX that I was considering but felt that Dialga and aegislash both out class this pokemon as an attacker. I could use those two spots for mewtwo EX, or try to get raichu or beartic in the deck.
