torch, multiple man, and vulture are the cards you want to move
forge and hulkbuster are there to help buff multiple man, which is essential for making him valuable
iron fist, cloak, dr strange, and heimdall are there for actually moving the cards
beast is there to help in sticky situations where your board is clogged, as well as duplicating stuff like iron fists effects. can also help "move" cards that are stuck, without actually applying the buff.
kraven is a passive receiver of buffs, if he moves on a turn, all the other cards that moved with him apply to his buff, meaning you can guarantee 2-3 buffs with heimdall.
dagger is new still, but i imagine you can kind of place her towards the end and just get a free +6-8 from heimdall at the end, or be used early if you dont draw anything better
i think this deck is super super neat :)
