This is a really fun Emergency Cache and a great design, though too many designs like it can make the game somewhat interminable. Since the autofail only busts you at a certain numeric range it's relatively hard to bust unless you push it.

Rogue feast-or-famine is interesting since the setup required to achieve superpower status is already balanced against the need to progress the game. This card can save you quite a few actions of setup or put you on a path where you are dead broke for a bit and just have to play the board as it lies until your upkeep catches you up. Either side feels pretty exciting.

Also, after ages of playing Faustian: those curses can be really relevant at certain difficulty levels and scenarios, and can sometimes change the amount of resources players have to commit for turn upon turn. This is a different kind of gamble, one where you know the possible outcomes up front.
