THB: Thassa's Oracle (Extended Art) holidaypuzzle Enchant artifact At the beginningWhen Thassa's Oracle enters, look at the top X cards of your library, where X is your devotion to blue. Put up to one of them on top of your library and the rest on the bottom of your library in a random order. If X is greater than or equal to the number of cards in your library, you win the game.
