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, Bridge from Below 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 Bridge from Below trigger, creating a creature token.
7. Repeat.
