Herd Baloth + Sadistic Glee + Umbral Collar Zealot

Herd Baloth

Sadistic Glee

Umbral Collar Zealot

How it works

1. Activate Umbral Collar Zealot by sacrificing any other creature.
2. When the creature dies, Sadisitc Glee triggers, putting a +1/+1 counter on Herd Baloth.
3. Herd Baloth triggers, creating a 4/4 Beast creature token.
4. Resolve the Umbral Collar Zealot ability, putting a +1/+1 counter on it.
5. Repeat.

This clever loop transforms a simple sacrifice outlet into an engine by letting Umbral Collar Zealot feed your graveyard while continuously turning the gears of death. Every time you sacrifice a creature to the Zealot, the death triggers Sadistic Glee to place a +1/+1 counter onto Herd Baloth. That influx of counters instantly fulfills the Baloth's trigger condition, spawning a fresh 4/4 Beast token that can immediately be fed back into the Zealot to keep the cycle spinning infinitely.
