Beifong's Bounty Hunters + Ashnod's Altar + The Skullspore Nexus

Beifong's Bounty Hunters

Ashnod's Altar

The Skullspore Nexus

How it works

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