Screams from Within + Umbral Collar Zealot + Tormod, the Desecrator

Screams from Within

Umbral Collar Zealot

Tormod, the Desecrator

How it works

1. Activate Umbral Collar Zealot by sacrificing the creature that has Screams from Within attached.
2. When the creature dies, Screams from Within triggers, returning it from your graveyard to the battlefield attached to another creature you control.
3. Tormod triggers, creating a creature token.
4. Resolve the Umbral Collar Zealot ability.
5. Repeat.

This elegant loop uses Umbral Collar Zealot's ability to repeatedly sacrifice a creature enchanted by Screams from Within, turning your own board into an endless engine of death and sacrifice triggers. Each time the enchanted creature perishes, Screams from Within triggers its own recursion to jump straight back from your graveyard to the battlefield, setting off Tormod, the Desecrator with every single card that leaves your graveyard to flood the board with tapped Zombie tokens. Meanwhile, Umbral Collar Zealot keeps the process fueled and smooth by surveilling through your library with every sacrifice.
