Mike Krahulik of Penny Arcade fame is working on a card game with Cryptozoic.

In Thornwatch enemies deal wound cards that get shuffled into your deck and since they cannot be discarded begin to build up in your hand. When a vampire picked a wound card from a player the vampire was healed and the wound card went back to the player. They could also smell blood so I let them teleport to any player who had a wound in their hand. When a player hit a vampire they could choose to either deal damage or strip off one of the vampire’s buff cards. It made for some fun choices and I could not have been happier with the way they worked.

Color me intrigued.
