Gregorius the Necromancer

Whenever a creature is dealt combat damage by
a Zombie token you control, that creature doesn't
untap during its controller's next untap step.
At the beginning of each opponent's precombat
main phase, if that player controls three or more
tapped creatures, venture into the dungeon.
{1}{w/b}, {t}: Exile target creature card from a
graveyard. If you do, create two 1/1 Black Zombie
creature tokens named Crawling Limb.
