Remove target enchantment from the game. Search its controller's graveyard, hand, and library for all cards with the same name as that enchantment and remove them from the game. That player then shuffles his or her library.

Crystal Keep Rulings Summaries

• Does not remove other cards of the same name from play. Just from the graveyard, hand, and library. [D'Angelo 1999/06/01]
• You look in that player's zones, but do not have to pick all instances of those cards if you don't want to. See Rule G19.4. Similarly, if you miss one in your search, you don't get to say you should have found it when it later turns up. [D'Angelo 2005/12/01]
• Note - Cycle with Eradicate, Quash, Sowing Salt, and Splinter.
