Staff of Eden, Vault's Key

Description

Staff of Eden, Vault's Key (ACR-260 Etched Foil) is a Legendary Artifact from the Assassin's Creed expansion. When it enters the battlefield, it returns a target legendary permanent card (other than itself) from a graveyard to the battlefield under your control. It also has an activated tap ability that lets you draw a card for each permanent you control but don't own, enabling unusual card advantage and synergy with tokens or stolen permanents.
