When this creature enters, you may exile target artifact or enchantment. When this creature leaves the battlefield, return the exiled card to the battlefield under its owner's control.
Imprint — When this artifact enters, each player exiles the top three cards of their library. Whenever a player casts a spell from their hand, that player exiles it. If the player does, they may cast a spell from among other cards exiled with this artifact without paying its mana cost.
