Timeless Witness

When this creature enters, return target card from your graveyard to your hand.
Eternalize (, Exile this card from your graveyard: Create a token that's a copy of it, except it's a 4/4 black Zombie Human Shaman with no mana cost. Eternalize only as a sorcery.)

Intent: We'd like to re-imagine the Eternal Witness as an initiate on Amonkhet.
