Ward

Devour land 3 (As this creature enters, you may sacrifice any number of lands. It enters with three times that many +1/+1 counters on it.)

When this creature enters, look at the top X cards of your library, where X is this creature's power. Put any number of land cards from among them onto the battlefield tapped, then shuffle.
