Sherry Barnett

When Sherry Barnett 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.)
