The Oracle

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.)
