Azusa, Wandering Scribe

When Azusa, Wandering Scribe enters the battlefield, look at the top three cards of your

them and put that card into your hand. Put the
rest on the bottom of your library in a random
order.
At the beginning of each end step, if you control
five or more lands with different names, flip
Azusa, Wandering Scribe.
