I'd say you need 3 allies doing 2 THW or 2 ATK in play to feel good about playing this card from hand, but there is a lot higher upside if built around with readying effects like Command Team or Avengers Assemble!. I don't think you need to worry too much about getting a side scheme in the victory display since this isn't an early-game card anyways. There are probably better options if you're only looking to use this "fairly" as a bit of healing value, but for a deck built around it, it can enable some crazy combo turns.
