Sly Requisitioner + Salvaging Station + Arcbound Ravager + Sol Ring

Sly Requisitioner

Salvaging Station

Arcbound Ravager

Sol Ring

How it works

1. Activate Sol Ring by tapping it, adding CC.
2. Activate Arcbound Ravager by sacrificing Sol Ring.
3. Sol Ring leaves the battlefield, triggering Sly Requisitioner, creating a 1/1 Servo artifact creature token.
4. Resolve the Arcbound Ravager ability, putting a +1/+1 counter on it.
5. Activate Arcbound Ravager by sacrificing the Servo.
6. The Servo dies, triggering Salvaging Station, untapping Salvaging Station.
7. Resolve the Arcbound Ravager ability, putting a +1/+1 counter on it.
8. Activate Salvaging Station by tapping it, returning Sol Ring from your graveyard to the battlefield.
9. Repeat.

This delightful loop is anchored by Salvaging Station, which uses its tap ability to continually fish Sol Ring back out of the graveyard whenever a creature bites the dust. To fuel that recursion, Arcbound Ravager gladly sacrifices the newly returned Sol Ring, which simultaneously triggers Sly Requisitioner to instantly replace it with a fresh Servo token. Sacrificing that very Servo back to Arcbound Ravager triggers Salvaging Station to untap itself, resetting the entire engine to pull Sol Ring right back out of the dirt.
