Caesar, Ape Leader

Caesar, Leader Of The Apes's power is equal to the amount of Apes you control.
Whenever an Ape creature enters the battlefield under your control, draw a card.
If you would draw a card, you may instead reveal cards from the top of your library until
you reveal a land, put it into your hand, and put
all other cards revealed this way on the bottom
of your library in any order.
