Rocket shows off his combat skills.

Professor X and Psylocke help you flip to alter ego, and you want to flip down to tinker or use Hall of Heroes. If you tinker and hall of heroes on the way up, you could be in hero form with 11 cards in hand!

Two-Gun Kid really helps to deal excess damage with your basic or the Rocket Launcher. Melee for weaker minions, but you can also use Warrior Skill with it to deal 4 and 4 which is really good. Rocket makes a TON of attacks, letting you brun through Warrior Skills, and it makes you heal more with Schadenfreude, but you also have access to alter ego.

Martial Prowess is good for Drop Kick, which you aim at the villain, and it helps you survive. I think rockets biggest weakness is he is a cute squishy racoon, but through Schadenfreude, Throg and Groot, plus extended access to alter ego. Rocket has good basic thwarting, and you have even more with Into the Fray. If you deal excess damage with Clobber and it is the first card you have played, you end up with 1 less card in your hand, and a dead minion.

I generally grab a Battery Pack when Salvageing, but if you lose the Particle Cannon, or you have a ton of minions in front of you Rocket Launcher can also be a good call. I did consider Boot Camp, but Throg will usually only attack once, Professor X will not attack, and Groot will defend, so it would only effect 4 allies, and at that point I think it is not worth it.
