2. When the creature dies, Beifong's Bounty Hunters triggers, earthbending a land.
3. Resolve the Phyrexian Altar ability.
4. Activate Phyrexian Altar 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.
