I would call this the Vicious Blow/Deduction of Survivor. Pretty much an auto-include.
For me this card is one of the strongest Survivor cards out there, maybe even the game, and really defines the class. Being able to recur any card from your discard is just so helpful. It doesn't even cost an action, just a successful test (generally on your turn due to the icons it possesses).
It's part of so many combos. Think of this card as the 3rd and 4th copies of your strongest cards - whether thats a Will to Survive, Look What I Found, Lucky! or anything else that your deck does.... it just multiplies the value of those cards. Not sure what you want? Hold it for later! You are never unhappy to see this card.
This goes in virtually every Survivor deck that I've built, with the exception of Patrice Hathaway. It's just that strong.
It does have limitations. It can only be used to recur Survivor Cards. This generally means that off-class survivors aren't interested in this card. You also need to succeed a test. Most likely this means an evade, and you can get screwed.
