Zodiacal Order

When Zodiacal Order enters the battlefield, search anywhere for exactly 12 creature cards and reveal them. Then, exile them in an ordered pile.
At the beginning of your upkeep, put the top card of the pile on the bottom of the pile.
At the beginning of each player's upkeep, each player may have a creature they control gain a keyword or activated ability in the text of the top card of the pile.
