Skittering Precursor + Sword of the Meek + Godhead of Awe + Umbral Collar Zealot

Skittering Precursor

Sword of the Meek

Godhead of Awe

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 Godhead of Awe, 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. Repeat.

This intricate loop turns a humble graveyard recursion trick into a self-sustaining engine. With Godhead of Awe shrinking all other creatures to base 1/1s, any Eldrazi Spawn token you create naturally satisfies the condition to trigger Sword of the Meek right out of your graveyard. By feeding that very Sword to Umbral Collar Zealot, you trigger Skittering Precursor to spawn a brand-new token, which immediately resurrects the Sword and leaves behind an Eldrazi Spawn mana source to keep the cycle going forever.
