I think this card having icons is a mistake, faustian bargain is by most accounts a very strong card, like obscenely strong, it makes its way into almost every deck I make even if team mates don't want curses the idea of gaining 5 resources from me is too tempting.
That said the idea that when you are fully set up and you can afford to not play this card and keep the curses at bay you don't even have to consider this a dead card, will and intellect tests are endlessly being made so you will just commit this in the late game, I feel like that's a mistake, can you just say no to the bargain and go on with your life?
Like any true evil bargain it should be there....tempting you, begging you to play it "its only two curses...come on, you can handle that can't you.... and you need the money, what if you draw something expensive and need it out fast?"
Like all cards that channel dark forces, faustian bargain proves there is a reason the good guys are always on the back foot, evil just get the best toys.
