Dross Scorpion + Detective's Satchel + Extruder

Dross Scorpion

Detective's Satchel

Extruder

How it works

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

This clever loop centers around Detective's Satchel, which generates a 1/1 Thopter artifact creature token whenever you tap it, provided you've sacrificed an artifact that turn. Extruder steps in to feed this engine, letting you sacrifice that very Thopter to grow your board with +1/+1 counters while satisfying the Satchel's condition for the next activation. Meanwhile, Dross Scorpion acts as the mechanical heart of the machine: every time your artifact creature dies, its untap trigger springs the Satchel back to life, ready to tap again.
