Venom, Eddie Brock + Animation Module + Pitiless Plunderer + Yahenni, Undying Partisan

Venom, Eddie Brock

Animation Module

Pitiless Plunderer

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing any other creature you control.
2. When the creature dies, Venom and Pitiless Plunderer trigger.
3. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
4. Activate the Treasure by tapping and sacrificing it, adding 1.
5. Resolve the Venom trigger, putting a +1/+1 counter on it.
6. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
7. Resolve the Yahenni ability.
8. Repeat.

This loop transforms simple creature sacrifices into a self-sustaining engine by tying together death triggers, mana generation, and counter production. When you use Yahenni, Undying Partisan to sacrifice a creature, Pitiless Plunderer immediately funds the process by creating a Treasure token that you can crack for mana. At the same time, Venom, Eddie Brock grows larger from the death and triggers Animation Module to automatically churn out a fresh Servo token for Yahenni's next meal.
