Skittering Precursor + Sword of the Meek + Raiders' Spoils + Umbral Collar Zealot

Skittering Precursor

Sword of the Meek

Raiders' Spoils

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 Raiders' Spoils, 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 engine transforms graveyard recursion into an endless loop by leveraging Raiders' Spoils to pump your freshly minted tokens to 1/1s. When Umbral Collar Zealot sacrifices Sword of the Meek, Skittering Precursor steps in to replace that sacrifice with a 0/1 Eldrazi Spawn token. Because Raiders' Spoils grants your creatures +1/+0, that Eldrazi Spawn enters as a 1/1, instantly triggering Sword of the Meek to leap straight from your graveyard back onto the battlefield equipped to the token. This creates a perpetual cycle of sacrifices and returns that fuels your mana and surveil triggers infinitely.
