Beifong's Bounty Hunters + Ashnod's Altar + Magus of the Bridge

Beifong's Bounty Hunters

Ashnod's Altar

Magus of the Bridge

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, Magus of the Bridge 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 Magus of the Bridge trigger, creating a creature token.
7. Repeat.
