Oh wow, this could be op in a game, but you balanced it out well with Vertigo.

Thanks! Yeah, I like the allure of a shiny thing that has a big risk/reward choice to make. I figure it's not something anyone would want to use frequently, but it's a cool tale to tell. And, as with all these cards, I think some of the vagueness leaves a lot for the GM to work with in terms of making it work for their game in a way that isn't broken.
