Extremely Niche. In order for this to be on par with Crisis Averted your character needs total stat-line of 9. This typically limits options to characters like Spider-Woman or Cable that can get 3-3-3 fairly consistently. At that point for 3-cost this card strips 9 threat from a target and exhausts you removing your ability to basic thwart for 3. So, subtracting the opportunity-cost of your basic thwart the overall value is 3-cost for 6 thwart. With Spider-Woman this could be better than Crisis Averted since she can technically reach a 4-4-4 statline, has access to several readies, has wild resource generators, and this could consistently turn Overwatch into a 0 for 9. If you are the sole thwarter in a multiplayer game running very specific heroes, this card could be a good include.
