Avacyn, Human

When this creature dies, search your library
for a creature named Avacyn and put it onto the battlefield. Then destroy all other creatures.
When a creature dies while this card is in the
graveyard, you may return all creatures other than
this card from all graveyards to the battlefield
under your control.
Avacyn was once human, like most, but lived such a
pure life so she inhabited all that is holy, all that is righteous, all that is Avacyn.
