Beifong's Bounty Hunters + Yahenni, Undying Partisan + The Necrobloom

Beifong's Bounty Hunters

Yahenni, Undying Partisan

The Necrobloom

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, The Necrobloom triggers, creating a creature token.
7. Resolve the Yahenni ability.
8. Repeat.

This loop turns Yahenni, Undying Partisan into an endless sacrifice engine by leaning on Beifong's Bounty Hunters to weaponize creature deaths into earthbending triggers. When you sacrifice an animated land, Beifong's Bounty Hunters's replacement effect whisks it back to the battlefield tapped, immediately triggering The Necrobloom's landfall ability to generate fresh fodder. Meanwhile, The Necrobloom also passively grants your graveyard-dwelling lands dredge 2, ensuring you never run out of resources to feed into the cycle.
