Enduring Renewal + Deathrender + Umbral Collar Zealot

Enduring Renewal

Deathrender

Umbral Collar Zealot

How it works

1. Activate Umbral Collar Zealot by sacrificing the creature with Deathrender attached.
2. When the creature dies, Enduring Renewal and Deathrender trigger.
3. Resolve the Enduring Renewal trigger, returning the creature from your graveyard to the battlefield.
4. Resolve the Deathrender trigger, putting the creature from your hand onto the battlefield, and attaching Deathrender to it.
5. Resolve the Umbral Collar Zealot ability
6. Repeat.

This loop turns your graveyard and hand into a revolving door of endless triggers, orchestrated by Enduring Renewal keeping your creatures from ever truly staying dead. Whenever you sacrifice a creature wearing Deathrender to Umbral Collar Zealot, Enduring Renewal instantly catches it on its way to the graveyard and bounces it right back to your hand. Meanwhile, Deathrender triggers upon that same death to sneak another creature from your hand directly onto the battlefield while snapping its equipment right back onto the newcomer, allowing the cycle to repeat indefinitely for infinite sacrifice, enter-the-battlefield, and surveil triggers.
