Beifong's Bounty Hunters + Yahenni, Undying Partisan + Rampaging Baloths

Beifong's Bounty Hunters

Yahenni, Undying Partisan

Rampaging Baloths

How it works

1. Activate Yahenni by sacrificing another nonland creature you control.
2. When the creature dies, Beifong's Bounty Hunters triggers, earthbending a land.
3. Resolve the Yahenni ability.
4. Activate Yahenni by sacrificing the land.
5. When the land dies, Beifong's Bounty Hunters triggers, returning the land from your graveyard to the battlefield tapped.
6. When the land enters, Rampaging Baloths triggers, creating a creature token.
7. Resolve the Yahenni ability.
8. Repeat.

This clever loop turns your own board into a self-sustaining engine by letting Beifong's Bounty Hunters continually animate, sacrifice, and return your lands. You start by using Yahenni, Undying Partisan's sacrifice ability on a nonland creature, which triggers the Bounty Hunters to earthbend a land into a 0/0 creature. Once that land-creature is sacrificed to Yahenni, the Bounty Hunters' replacement/return effect puts it right back onto the battlefield. Every time that land re-enters, Rampaging Baloths triggers to reward you with a fresh 4/4 Beast creature token that can be fed right back into Yahenni to keep the cycle going.
