Skittering Precursor + Sword of the Meek + Domri, Anarch of Bolas + Arcbound Ravager

Skittering Precursor

Sword of the Meek

Domri, Anarch of Bolas

Arcbound Ravager

How it works

1. Activate Arcbound Ravager 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 Arcbound Ravager ability, putting a +1/+1 counter on it.
5. Repeat.

This intricate engine relies on Domri, Anarch of Bolas to permanently pump your 0/1 tokens into 1/1 creatures, which is the crucial bridge that allows Sword of the Meek to trigger and recur itself from the graveyard whenever a fresh token arrives. Meanwhile, Skittering Precursor watches your permanent sacrifices and constantly replaces them with new Eldrazi Spawn to fuel the loop. By feeding that endless cycle into Arcbound Ravager, you can repeatedly sacrifice Sword of the Meek to grow your artifact menace into an infinitely massive threat while generating an endless supply of triggers and colorless mana.
