Beifong's Bounty Hunters + Thermopod + Skittering Precursor

Beifong's Bounty Hunters

Thermopod

Skittering Precursor

How it works

1. Activate Thermopod by sacrificing another nonland creature.
2. When the creature dies, Beifong's Bounty Hunters triggers, earthbending a land you control.
3. Activate Thermopod by sacrificing the earthbent land.
4. When the land dies, Skittering Precursor and Beifong's Bounty Hunters trigger.
5. Resolve the Beifong's Bounty Hunters trigger, returning the land from your graveyard to the battlefield.
6. Resolve the Skittering Precursor trigger, creating a creature token.
7. Repeat.

This elegant loop begins with Thermopod, whose ability lets you sacrifice a creature to generate red mana. Each time you feed a creature to Thermopod, Beifong's Bounty Hunters triggers to earthbend one of your lands into a massive 0/0 creature laden with +1/+1 counters. You can then sacrifice that same earthbent land directly to Thermopod, triggering a cascade of value: Beifong's Bounty Hunters smoothly returns the land to the battlefield tapped, while Skittering Precursor swoops in to create a colorless Eldrazi Spawn token every time a nontoken permanent is sacrificed. That very same Eldrazi Spawn can then be sacrificed to pay for Thermopod's activation or turned into colorless mana, sustaining an endless cycle of creature deaths, landfalls, and mana generation.
