This card, along with Focused Rage, are the two must-have cards you want to see in your opening hand.
She-Hulk is constantly flipping to take advantage of her passive threat interruption, as well as loading up another 2 damage for her next flip. You'll likely flip once a turn, meaning if you drop SLD on turn 1, you have a powerful threat-mitigation ability that will pay dividends all game.
You can remain focused on damage most of the game and still contribute 2 threat removal a turn so long as you have to throw out. This means a few First Aid to either heal allies or feed to SLD in your deck isn't a bad idea.
Notable interaction with Hellcat's resource:
If you are playing Leadership yourself, or have a Leadership buddy with Get Ready available - install Hellcat - thwart 2 - Get Ready - thwart 2 - bounce to hand - use her resource and send her to work some caseload. That's 6 thwart on a turn you could still activate twice.
The price is perfect, its limitations are easy enough to plan around, and it'll provide balanced momentum all game long.
