If "Eureka!" is in play, send it to its owner's Boot Hill. Attach Eureka! to the home of the player to your left. When Eureka! attaches to a player's home, the player discards one card from his or her Play hand. A player's maximum hand size is reduced by one while Eureka! is attached. If the player wins a shootout, Eureka! leaves and attaches to the next player on the left. Only one Eureka can be in play at a time - discard any subsequent copies.
