Wakako Okada

When this creature 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. (Each {u} in the mana costs of permanents you control counts toward your devotion to blue.)
