Urza's Destiny

When enchanted creature is put into a graveyard from play, that creature's controller may search his or her library for a creature card and put that card into play. If that player does, he or she then shuffles his or her library.

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.

Searching for a creature card is optional.
