Rare

Illus. Jeff A. Menges

10/4/2004: The land put onto the battlefield does not count toward your one per turn limit because it was put onto the battlefield by an effect.
10/4/2004: Because the "search" requires you to find a card with certain characteristics, you don't have to find the card if you don't want to.
