Requires a few pool 3 cards which I got lucky to get by 1000ish collection level.
Absorbing Man is key here.
I used to run the same deck list without him and adding him made a HUGE difference to this deck. He is so damn versatile it's incredible. It makes the deck just click! You can copy so many important effect. Need another Cloak? You got it. Another Doctor Strange? There you go! Or Aero on 5 AND 6! That's a game winning play almost every time!
Dagger is alright in this deck. I could consider swapping her out but you really need 3 moving cards. Multiple man is an absolute NO. You'll fill up your board and will end up killing your Heimdall potential.
Also important note: Absorbing Man can't copy Hulk Buster unfortunately since the card he copy the effect from needs to be on the board.
