I have always liked the connection of Skuntank G and Mightyena PL to poision both actives and then do up to 80 damage for 0 energy! I have made a draft decklist, though it can still be improved. It hasn't lost a game yet either (Pleayed against Genagr, Empoleon and Turtwig GL). Any help is appreciated!

Strategy:
Try to go for the first turn KO with Skuntank, Broken Time Space, Poochyena and Mightyena. You can do 80 (90 with poison damage) on your first turn this way, perhaps scoring you a turn 1 KO. If it goes longer, however, just swarm with Mightyena with no energy for continual KO's. LA Mightyena's 'Bite Ok' attack stops basics (Like Sp's) from attacking, retreating or using any pokepowers during there next turn, really hitting hard on SP decks. Against Dialga G X, which shuts down Mightyena's body, use Houndoom for the 1HKO. Toxicroak can counter Machamp and also combo's nicely with Skuntank's Power.
