Extruder + Wingrattle Scarecrow + Sigil Captain

Extruder

Wingrattle Scarecrow

Sigil Captain

How it works

1. Activate Extruder by sacrificing Wingrattle Scarecrow
2. When Wingrattle Scarecrow dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Wingrattle Scarecrow enters, Sigil Captain triggers, putting a +1/+1 counter on Wingrattle Scarecrow
4. Resolve the Extruder ability.
5. Repeat.

This ingenious loop relies on a clever interplay between counters and creature stats to build an unstoppable engine. Wingrattle Scarecrow serves as the sacrificial heart of the combo, exploiting its persist ability to return from the grave while carrying a neutralizing -1/-1 counter. Enter Sigil Captain, whose static ability instantly recognizes the returning scarecrow as a 1/1 creature, immediately showering it with two +1/+1 counters that neatly wipe away the -1/-1 counter. Finally, Extruder provides the reusable sacrifice outlet that fuels the cycle, turning every iteration into a chance to distribute a fresh +1/+1 counter wherever you need it most.
