Skittering Precursor + Sword of the Meek + Domri, Anarch of Bolas + Umbral Collar Zealot

Skittering Precursor

Sword of the Meek

Domri, Anarch of Bolas

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 Domri, 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 clever recursive loop turns a modest artifact into an unstoppable engine by exploiting a clever size modification. When you use Umbral Collar Zealot to sacrifice Sword of the Meek, Skittering Precursor triggers to replace your lost permanent with an Eldrazi Spawn token. Because Domri, Anarch of Bolas passively pumps your creatures with a +1/+0 buff, that newly spawned 0/1 token enters the battlefield as a 1/1, which immediately satisfies Sword of the Meek's resurrection condition and loops the sword right back to the battlefield attached to your token. You can repeat this process as many times as you like, fueling an infinite stream of sacrifices, death triggers, and surveil while generating infinite colorless mana from your Eldrazi Spawn tokens.
