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

Skittering Precursor

Sword of the Meek

Nahiri's Resolve

Extruder

How it works

1. Activate Extruder 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 Extruder ability, putting a +1/+1 counter on a creature you control.
5. Repeat.

This clever loop turns Extruder into a relentless engine by utilizing Sword of the Meek as permanent fodder that continuously recycles itself. Whenever you feed the Sword to Extruder, Skittering Precursor steps in to replace it with an Eldrazi Spawn token. Crucially, Nahiri's Resolve passively grants your creatures +1/+0, turning that newly arriving 0/1 token into a 1/1 as it enters the battlefield. That stat boost is the secret ignition key, satisfying Sword of the Meek's trigger condition so it leaps straight from your graveyard back onto the battlefield, ready to be sacrificed to Extruder all over again for an endless cascade of counters, mana, and triggers.
