When Gisa and Geralf enters, mill four cards. Once during each of your turns, you may cast a Zombie creature spell from your graveyard.

{1}, Sacrifice this artifact: Search your library for a basic land card, reveal it, put it into your hand, then shuffle.

As this creature enters, choose a creature type. This creature is the chosen type in addition to its other types. Each other creature you control of the chosen type enters with an additional +1/+1 counter on it.

Return target creature card from your graveyard to your hand. Put a +1/+1 counter on up to one target Zombie you control. Flashback {3}{B} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

When this creature dies, you may search your library for a card named Wretched Throng, reveal it, put it into your hand, then shuffle.

Grimgrin enters tapped and doesn't untap during your untap step. Sacrifice another creature: Untap Grimgrin and put a +1/+1 counter on it. Whenever Grimgrin attacks, destroy target creature defending player controls, then put a +1/+1 counter on Grimgrin.

As an additional cost to cast this spell, sacrifice a creature. Draw two cards.

Create two 2/2 black Zombie creature tokens. Madness {2}{B} (If you discard this card, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)

({T}: Add {B}.)
