[@Saber] Just making sure, you are going to be using a real deck of Tarot cards and what you draw is what the character draws correct? 

If so, maybe for major events, you separate the named cards (major stand alone cards as well as the pages, knights, queens, and kings of each) from the minor ones (Ace through 10 of each), and during those major events you shuffle the named cards and draw from them. Then for the rest you shuffle them together and pull as you would normally. Either way I think it's a cool idea and was thinking of making a character based on that myself *two thumbs up*
