Black Widow Returns the Favor

Hello fellows

My very first posted deck Have a lot of fun with it recently. Managed solo defeated Expert Thanos with it pretty easily

So, there are 2 gimmicks in the deck:

1. Return the Favor is a legend here. Combined with Grappling Hook it is guaranteed 6 dmg per 0 cost card.
2. Strong shield themed cards. As Med Team is also S.H.I.E.L.D. it is combined well with the rest shield cards like Government Liaison and Sky-Destroyer. It also is used to keep Agent 13 and Dum Dum Dugan on board for them to do their magic.

Also Judoka Skill + Synth-Suit +Attacrobatics is almost guaranteed free defense with 0 dmg received and ready Hero card after
