Printed Game Text: Played at the beginning of the player's turn, this card is not discarded. It affects all players and remains in effect until any other rule card is played.

Events that have a stated duration remain in effect. After two events have been played, a third event forces the first event played to be discarded. Events continue to cycle through, with a third event always replacing the event that has been active the longest.
