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.

Probably the best Basic ally in the game. Cheap, no restrictions, provides tangible benefit. She's removes a point of damage or threat and then chump blocks the villain. The block is hard to quantify, but I would gladly pay one resource to do a point of damage and prevent all damage from the villain for one turn.

Absolutely, any turn in the game. Ironheart ruled even before she was a proper hero.
