Beifong's Bounty Hunters + Thermopod + Seed the Land

Beifong's Bounty Hunters

Thermopod

Seed the Land

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, Seed the Land triggers, creating a creature token.
6. Repeat.
