Reward Deck

This variant uses all of the standard rules and victory conditions, with the exception of the following rules.
 * When a player receives cards as defender rewards, he or she may draw some or all of the cards from the reward deck.
 * Discarded reward cards go to a special reward deck discard pile. Not all game effects that target the regular discard pile, or the cards in it, will apply to the reward deck discard pile.
 * If an effect targets a card just before, while, or just after it is discarded (such as the Clone, the Fido, or the Vulch), then that effect does work on cards headed to either discard pile. However, something happening later that is not specifically responding to the discarding process (such as Delta Scanners or Space Junk) does not affect the reward deck discard pile; it is too late!
 * When the reward deck runs out, shuffle its discard pile to make a new reward deck. If the reward deck discard pile is also empty, then no further reward cards can be drawn until at least one reward card is discarded. The reward deck never causes a cosmic quake.
 * When selecting cards at random from a hand with both cosmic and reward cards, a player is allowed to choose which card backs he or she is targeting. In other words, “at random” means “without seeing the faces of the cards.”
