Doc Aurlock, Grizzled Genius + Planar Void + Eternal Scourge + Thermopod

Doc Aurlock, Grizzled Genius

Planar Void

Eternal Scourge

Thermopod

How it works

1. Activate Thermopod's second ability by sacrificing Eternal Scourge, adding .
2. When Eternal Scourge dies, Planar Void triggers, exiling Eternal Scourge from your graveyard.
3. Cast Eternal Scourge from exile by paying 1.
4. Repeat.

This ingenious loop turns a modest snow creature into a self-sustaining engine by leaning on a few key cost-reduction and exile mechanics. When you feed Eternal Scourge to Thermopod's sacrifice ability for red mana, Planar Void immediately intercepts the creature before it can settle in the graveyard, whisking it straight into exile instead. From there, Doc Aurlock, Grizzled Genius steps in to slash the cost of playing spells from exile, allowing you to recast Eternal Scourge for a mere single mana and repeat the entire process indefinitely.
