A Discard Pile is one of several areas that are used to place cards after they are played or discarded. The discard piles are used later as a source to retrieve cards of particular types. The discard pile at Rooney's Weapons Emporium contains used or discarded weapons. The discard pile at Weil's Pawn Shop contains killed or discarded bunnies. The discard pile at Kaballa's Market contains spent or discarded dolla.
If the game runs long enough that the draw pile runs out, all discard piles are combined and shuffled to replace the draw pile.
