Dross Scorpion + Detective's Satchel + Umbral Collar Zealot

Dross Scorpion

Detective's Satchel

Umbral Collar Zealot

How it works

1. Activate Detective's Satchel by tapping it, creating a 1/1 Thopter artifact creature token.
2. Activate Umbral Collar Zealot by sacrificing the Thopter.
3. When the Thopter dies, Dross Scorpion triggers, untapping Detective's Satchel.
4. Resolve the Umbral Collar Zealot ability.
5. Repeat.

This clever loop puts Dross Scorpion's relentless metal-crafting to work alongside Detective's Satchel, which happily produces a 1/1 Thopter artifact creature token whenever you need one—provided you've sacrificed an artifact that turn. Umbral Collar Zealot provides that crucial sacrifice outlet, letting you feed the Thopter back to the grave to fuel the Satchel's condition while surveiling your library. Because the Thopter is both an artifact and a creature, its demise triggers the Scorpion to untap Detective's Satchel instantly, resetting the engine for another cycle of endless sacrifice and discovery.
