Feexe, Cosmic Steward

Indestructible, Flying, Defender
If your Devotion to All colors is less than 15
Feexe isn't a creature.
Books you control have Hexproof.
You may tap three untapped books you control
to search your library for a book with a different
name and put it unto the battlefield tapped.
At the beginning of your upkeep if you untapped
at least 10 books with different names you win
the game.
