Of the seven heroes we've seen so far, she's my favorite in the comics. I really love her original Savage run.
In the card game, this looks like a really fun and different hero to play. She has a recover of 5 so she could do well with protection. She could tank and then Gamma Slam. But I'm also trying to build her around Great Responsibility. When building justice She-Hulk I'm probably not putting Heroic Intuition in there.
BTW, at the time I wrote this card review, she was mistakenly referred to as Jessica Walters on here. It's Jennifer Walters.
