So I collect cards.  Mostly for the art (because I suck at tricks, magic, and flurishes).  I like when there is a "back story" or game that goes along with the deck.  I got my Altruism deck before Sandy hit, and I ordered a few of the Smow Owls on Halloween.  I spent the weekend going over the deck trying to find the "secrets."  I also went through their FaceBook page and tried to find more there as well.  I still think I am missing something.

For me, it is fun as long as it is not in-my-face, not too hard, and has a decent payoff at the end (I guess I will have to wait until the 13th for more clues).
