Beifong's Bounty Hunters + Phyrexian Altar + Golgari Germination

Beifong's Bounty Hunters

Phyrexian Altar

Golgari Germination

How it works

1. Activate Phyrexian Altar by sacrificing another nonland creature.
2. When the creature dies, Beifong's Bounty Hunters triggers, earthbending a land you control.
3. Activate Phyrexian Altar by sacrificing the earthbent land.
4. When the land dies, Golgari Germination 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 Golgari Germination trigger, creating a creature token.
7. Repeat.
