OracletextImprint — When Thought Prison comes into play, you may have target player reveal his or her hand. If you do, choose a nonland card from it and remove that card from the game. <em>(The removed card is imprinted on this artifact.)</em>

Whenever a player plays a spell that shares a color or converted mana cost with the imprinted card, Thought Prison deals 2 damage to that player.
