Korvold, Fae-Cursed King

Animation Module

Pitiless Plunderer

Extruder

How it works

1. Activate Extruder by sacrificing another creature you control
2. When the creature dies, Pitiless Plunderer and Korvold's second ability trigger.
3. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
4. Holding priority, activate the Treasure by tapping and sacrificing it, adding 1.
5. Resolve the Korvold trigger, putting a +1/+1 counter on it and draw a card.
6. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
7. Resolve the Extruder ability.
8. Repeat.
9. Activate Extruder by sacrificing another creature.
10. When the creature dies, Pitiless Plunderer triggers, creating a Treasure token.
11. Activate the Treasure by tapping and sacrificing it, adding 1.
12. Resolve the Extruder ability, putting a +1/+1 counter on it.
13. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
14. Repeat.

This engine transforms Extruder's artifact sacrifice outlet into a self-sustaining loop by leveraging Pitiless Plunderer to translate creature deaths into Treasures, which conveniently supply the mana needed to keep going. Meanwhile, Korvold, Fae-Cursed King watches the sacrifices and counter placements to flood your hand with cards while growing massive, feeding cards directly into the cycle. Every time Korvold and Extruder add a +1/+1 counter, Animation Module steps in with its triggered ability to pay {1} using the Treasure's mana, spawning a fresh Servo token to be fed back into the grinder.
