Beifong's Bounty Hunters + Phyrexian Altar + Open the Graves

Beifong's Bounty Hunters

Phyrexian Altar

Open the Graves

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, Open the Graves 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 Open the Graves trigger, creating a creature token.
7. Repeat.
