Beifong's Bounty Hunters

Phyrexian Altar

Anax, Hardened in the Forge

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, Anax 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 Anax trigger, creating a creature token.
7. Repeat.
