First off, love the concept. I've been trying to get my wife to at least *try* the game, just once, for 14 years. Its nice to see someone succeed
Anyway, I'm guessing there's not a super cohesive mechanical theme to the deck? I'm seeing some Aristocrats elements, is that sort of the wincon you're angling for? Value through self sacrificing? My wife and I are also witches, so I'm with you on how resonant that concept is with your goal.
I don't want to start spitting out card names until I get your response, so I know a little more about what your mechanical goals for the deck are.
