Beifong's Bounty Hunters + Thermopod + Rampaging Baloths

Beifong's Bounty Hunters

Thermopod

Rampaging Baloths

How it works

1. Activate Thermopod by sacrificing another nonland creature you control.
2. When the creature dies, Beifong's Bounty Hunters triggers, earthbending a land.
3. Activate Thermopod by sacrificing the land.
4. When the land dies, Beifong's Bounty Hunters triggers, returning the land from your graveyard to the battlefield tapped.
5. When the land enters, Rampaging Baloths triggers, creating a creature token.
6. Repeat.
