Sorcery, 2GG (4) Remove target artifact from the game. Search its controller's graveyard, hand, and library for all cards with the same name as that artifact and remove them from the game. That player then shuffles his or her library.
Illus. Tsutomu Kawade
Does not remove other cards of the same name from play. Just from the graveyard, hand, and library. [D'Angelo 1999/06/01]
If you manage to turn a basic land (such as a Forest) into an artifact, you can indeed use this effect on that basic land type. [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]
