Undead Sprinter + Pitiless Plunderer + Thermopod

Undead Sprinter

Pitiless Plunderer

Thermopod

How it works

1. Activate Thermopod's second ability by sacrificing Undead Sprinter, adding .
2. When Undead Sprinter dies, Pitiless Plunderer triggers, creating a Treasure token.
3. Activate the Treasure by tapping and sacrificing it, adding .
4. Cast Undead Sprinter from your graveyard by paying .
5. Repeat.

This elegant loop turns the graveyard-recurrence of Undead Sprinter into a self-sustaining engine by utilizing Pitiless Plunderer to turn every death into a cashable asset. While Thermopod provides the necessary red mana through its sacrifice outlet, the Treasure generated by the Plunderer effortlessly bridges the color requirement to recast the Sprinter right back from the graveyard. Because the Sprinter is not a Zombie, its own demise conveniently keeps its conditional casting condition met, allowing you to cycle it endlessly for infinite sacrifice triggers and storm count.
