I think first of all 50 cards is too many. Try cut some of this. My suggestion is get 2 copies instead of 3 with some cards (Enhanced Awarness definitely, Preemptive Strike, Armored Vest).
or even get rid of (3 Haymakers? I know it is probably for Nova ability, but it is one of the worst cards if you think about economy (3damage for 3 ER), next example Armored Vest - Ms.Marvel should use herself for ability (return event) and not for weak defense. Maybe 7 allies is a little too much - you don't get enough resource for something like Luke Cage AND Lockjaw
So it is 41 cards which is a lot better. I hope, this will help :)
