Ozox, Tyrant of Bone

This creature can't block

When this creature enters or leaves the battlefield, exile your hand, graveyard, and all other permanents you control. Then mill cards equal to the non-token cards exile this way. Return all lands from your graveyard to the battlefield and up to 7 cards from your graveyard to your hand, shuffle all cards you own in exile into your library, then exile cards from your graveyard equal to the number of lands
you control at random.
