She-Hulk and friend

Before we go any further, this is explicitly a multiplayer deck. It is built around one of the other players being able to play Honorary X-Men onto Spider Woman. There is a good Guardian build too I might link later if no one is playing an X-Men hero.

Your goal is to build up the She-Hulk ally into an absolute monster. Play every single attachment on her. Heal and ready her as many times as you can with Game Time, Triage, First Aid, Sky Cycle, etc.

When you're all built out, She-Hulk can be gamma slammin' for 21+ per attack, 3 or 4 times in a turn. Every HP she gets is a future damage counter and +1 ATK.

Step 1. Play She-Hulk. I usually keep 1 expensive card like Boot Camp, Team Training, etc and mulligan the rest of my starting hand to find She-Hulk, Call for Aid, Suit Up, or Jessica Drew's Apartment. Your absolute only priority is getting She-Hulk into the table.

Step 2. Play all of the upgrades on She-Hulk, get Boot Camp, Team Training, etc out.

Step 3. ????

Step 4. Profit. Attack over and over again. each attack makes her stronger for the next one.

Pro tips: I would recommend healing whenever it's convenient, even if she's not almost dead, even though that takes away some damage. You don't want to get caught later with multiple readies in hand and no spare HP.

Save Enraged for the late game.

Power Gloves is great for pinging off tough cards for your next target.

Depending on how much you value consistency and how many copies of Honorary X-Men the other players are packing, you might want to bring up to 1. more copy of each/any of the Honorary cards. You need S.H.I.E.L.D. to play Bambino and you can only play S.H.I.E.L.D. Deputy in alter ego. If you pack two you can play one on yourself before you have She-Hulk out so that you can play the next one on her even in Hero form.
