The Sibsig Ceremony

Enchant player

Whenever a land enchanted player controls enters, you create a 2/2 black Zombie creature token with decayed. (It can't block. When it attacks, sacrifice it at end of combat.)

Whenever this creature or another nontoken Zombie you control dies, create a 2/2 black Zombie creature token.

This creature enters with a +1/+1 counter on it for each Zombie card in your graveyard.

Whenever you cast a Zombie spell, create a tapped 2/2 black Zombie creature token.

Noncreature spells you cast cost less to cast.

Whenever you cast a noncreature spell, counter that spell unless you sacrifice a creature.

Whenever this creature or another Human creature you control dies, create a tapped 2/2 black Zombie creature token.

Morbid — When this creature enters, if a creature died this turn, create a 2/2 black Zombie creature token.
