Beifong's Bounty Hunters + Umbral Collar Zealot + Field of Souls

Beifong's Bounty Hunters

Umbral Collar Zealot

Field of Souls

How it works

1. Activate Umbral Collar Zealot by sacrificing another nonland creature.
2. When the creature dies, Beifong's Bounty Hunters triggers, earthbending a land you control.
3. Resolve the Umbral Collar Zealot ability.
4. Activate Umbral Collar Zealot by sacrificing the earthbent land.
5. When the land dies, Field of Souls and Beifong's Bounty Hunters trigger.
6. Resolve the Beifong's Bounty Hunters trigger, returning the land from your graveyard to the battlefield.
7. Resolve the Field of Souls trigger, creating a creature token.
8. Resolve the Umbral Collar Zealot ability.
9. Repeat.

This clever loop turns Umbral Collar Zealot into a relentless sacrifice engine by leaning on the passive generation of replacement material and the unique mechanics of earthbending. Whenever you feed a creature to the Zealot, Beifong's Bounty Hunters triggers to animate a land into an earthbent creature, which you can then sacrifice right back into the engine. Meanwhile, Field of Souls acts as a steadfast factory, replacing your sacrificed living creatures with 1/1 white Spirit tokens to keep the sacrificial cycle spinning endlessly.
