Nazahn, Revered Bladesmith

When Nazahn, Revered Bladesmith enters the battlefield, search your library for an Equipment
card and reveal it. If you reveal a card named
Hammer of Nazahn this way, put it onto the
battlefield. Otherwise, put that card into your
hand. Then shuffle your library.
Whenever an equipped creature you control
attacks, you may tap target creature defending
player controls.
