Skittering Precursor + Sword of the Meek + Nahiri's Resolve + Sarcatog

Skittering Precursor

Sword of the Meek

Nahiri's Resolve

Sarcatog

How it works

1. Activate Sarcatog 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 Nahiri's Resolve, Sword of the Meek triggers, returning Sword of the Meek from your graveyard to the battlefield attached to the Eldrazi Spawn.
4. Resolve the Sarcatog ability, giving it +1/+1 until end of turn.
5. Repeat.

This clever loop relies on Nahiri's Resolve to passively boost the humble 0/1 Eldrazi Spawn tokens produced by Skittering Precursor into 1/1 creatures the moment they enter the battlefield. That crucial stat bump allows the returning Sword of the Meek to constantly trigger itself from the graveyard, automatically reattaching to each newly minted Spawn. Meanwhile, Sarcatog acts as your reliable outlet by sacrificing the Sword of the Meek to fuel its own growth while simultaneously feeding the Skittering Precursor's trigger mechanism over and over again.
