Black Claw Ranger

When Black Claw Ranger enters the battlefield,
search your library and/or graveyard for a card
named Black Claw and put it onto the battlefield.
If you searched your library, then shuffle your
library.
Whenever Black Claw Ranger attacks, Black
Claw also attacks. If no other creatures attack
with them, then tap a creature defending player
controls. That creature doesn't untap on its controller's next untap step.
