Thassa's Oracle

Thassa's Oracle {U}{U}

Creature - Merfolk Wizard | Power/Toughness: 1 / 3 (CMC 2)
When Thassa's Oracle enters the battlefield, 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. (Each {U} in the mana costs of permanents you control counts toward your devotion to blue.)
