Is that you Maria Hill?Ironheart's Response ability draws a card, so she is effectively a 1 cost card as she replaces herself, netting you 2 THW/ATK or 1 THW/ATK & a chump block for 1 net card. As a Comparable basic version of Maria Hill, Ironheart has 1 less thwart and her Response only draws a card for you and not for other players (doesn't matter in solo, only in multiplayer), but being compared to an aspect staple is not a bad thing. She is currently the cheapest basic ally available as well. If you need to dig or value card draw this is decent value. For non-leadership decks this a Maria Hill stand-in. For leadership decks, this can be a Maria Hill understudy.
I also like to compare Ironheart to Mockingbird. — L3w15 7 · 3254
Mockingbird does 2atk/thw and "blocks" 2 attacks for 4ER. Ironheart does 1atk/thw and blocks 1 attack for 2ER. That basically makes Ironheart do half the effect for half the cost. And given that mockingbird is very strong, Ironheart is too. — L3w15 7 · 3254
