Necrosan, Aurora of Death

Flying, deathtouch
Whenever a creature with a hatred counter on it
dies, you may pay {x}{w/b}{w/b}, where X is that
creature's toughness. If you do, return that
creature to the battlefield under your control. It's
a Dragon Zombie in addition to its other types.
"There is no need to cry, child. By my blade, you
shall be put to rest. By my hand, you will be reborn as something greater."
