Staff of Eden, Vault's Key

Description

Staff of Eden, Vault's Key (ACR 123) is a legendary artifact from the Assassin's Creed expansion. When it enters the battlefield you may return a target legendary permanent card (other than itself) from a graveyard to the battlefield under your control, providing powerful recursion. It also has a {T} ability that draws you a card for each permanent you control but don't own, enabling unusual card draw and political effects in multiplayer or deck-swap scenarios.
