Ravenous Ooze

Deathtouch
At the beginning of your upkeep, destroy target non-Ooze permanent an opponent controls, its controller creates a token that is a copy of Ravenous Ooze. If you can't, sacrifice Ravenous Ooze and return a permanent card from your graveyard to your hand.
The ooze feeds upon the land and the land feeds upon the ooze.
