Jetmir, Nexus of Revels + Skittering Precursor + Sword of the Meek + Umbral Collar Zealot

Jetmir, Nexus of Revels

Skittering Precursor

Sword of the Meek

Umbral Collar Zealot

How it works

1. Activate Umbral Collar Zealot by sacrificing Sword of the Meek.
2. Skittering Precursor triggers, creating a 0/1 Eldrazi Spawn creature token.
3. When the Eldrazi Spawn enters the battlefield as a 1/1 due to Jetmir, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Eldrazi Spawn.
4. Resolve the Umbral Collar Zealot ability
5. Activate the Eldrazi Spawn by sacrificing it, adding C.
6. Repeat.

This ingenious engine loops right out of your graveyard by using Umbral Collar Zealot to sacrifice Sword of the Meek, which triggers Skittering Precursor to churn out an Eldrazi Spawn. Because Jetmir, Nexus of Revels pumps your team, that newly arriving token hits the battlefield as a 1/1, instantly satisfying the resurrection condition that brings Sword of the Meek right back to attach itself. Along the way, the Eldrazi Spawn can be sacrificed for mana to keep the cycle going, giving you an endless supply of triggers and surveils.
