The Key to the Vault

Description

The Key to the Vault (POTJ-54p, foil) is a Legendary Artifact — Equipment from Outlaws of Thunder Junction Promos. Whenever the equipped creature deals combat damage to a player, you may exile a nonland card from the top of your library equal to that damage and cast it without paying its mana cost. It equips for {2}{U}, enabling a blue value engine that rewards successful combat damage by potentially cheating spells into play.
