Dross Scorpion + Detective's Satchel + Krark-Clan Grunt

Dross Scorpion

Detective's Satchel

Krark-Clan Grunt

How it works

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

This looping engine uses Detective's Satchel as a repeatable token factory, letting you tap it to create a 1/1 Thopter as long as an artifact was previously sacrificed that turn. You then feed that newly minted Thopter directly into Krark-Clan Grunt, pumping its power while triggering Dross Scorpion's crucial death ability. Because the Thopter is an artifact creature, its demise causes Dross Scorpion to untap Detective's Satchel, resetting the entire loop and allowing you to churn through endless sacrifice and entry triggers.
