This is the classic standard in threat removal events, the signature Justice event. The ability to remove four threat for only three effective resources is impressively and unusually efficient for an aspect event. A lot of the time, when I'm playing the game and being pressured by a scary opponent with dangerous schemes, this is exactly the card I am most hoping to draw. It is impressive how good Justice decks can be at being able to muster up the science resource for this card, it is really very common, and worth thinking a little about when you design the deck. And it is really cool how The Power of Justice combines absolutely perfectly with this card. The only reason I don't put this in every Justice deck is that I like to switch things up and have more variety, but there is a little something missing playing a deck that does not have this card.
Note that I play multiplayer scenarios against highly threatening opponents, where there is always a desperate need to remove four threat from something. This card could be somewhat less useful when playing solo, where you could actually run into the problem that it would be overkill against most of the side schemes.
