Beifong's Bounty Hunters + Thermopod + Thranduil the Strategist

Beifong's Bounty Hunters

Thermopod

Thranduil the Strategist

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. Resolve the Thermopod ability.
4. Activate Thermopod by sacrificing the land.
5. When the land dies, Beifong's Bounty Hunters triggers, returning the land from your graveyard to the battlefield tapped.
6. When the land enters, Thranduil the Strategist triggers, creating a creature token.
7. Repeat.
