Captain Marvel - Defender of Earth

Protection gets a bad rap, but it has a lot of energy cards and ways for Carol to reduce damage without actually defending, particularly with the addition of Perseverance from the new Wasp pack. This frees her up to thwart while building up Energy Channel. There is some mental energy for Black Widow, though tbh I don't think I've ever actually player her in this deck, so might be some room for dropping her in favor of something else.

Ironheart is no Maria Hill, but I think she's still great for non-leadership decks. The Power in All of Us will be great when you draw it with Quincarrier or Enhanced Reflexes or Mockingbird, but still useful as a wildcard energy you can use for some of Carol's signature cards.

So far, beaten Klaw, the Red Skull campaign, and expert Rhino without much trouble.
