Necromancer's Summon

Return up to two target creature cards from
your graveyard to the battlefield. Each of those
creatures is a black Zombie in addition to its
other colors and types. Put Necromancer's
Summon on the bottom of its owner's library.
"Fairy maidens that have fallen into the underworld.
Become corpses and wander through purgatory."
