Nether Traitor + Kheru Goldkeeper + Chalk Outline + Yahenni, Undying Partisan

Nether Traitor

Kheru Goldkeeper

Chalk Outline

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Nether Traitor.
2. Activate Yahenni by sacrificing another creature.
3. When the creature dies, Nether Traitor triggers, causing you to pay to return Nether Traitor from your graveyard to the battlefield.
4. Kheru Goldkeeper and Chalk Outline triggers, creating a Treasure token, Clue token and creature token.
5. Resolve the Yahenni ability.
6. Activate the Treasure by tapping and sacrificing it, adding .
7. Repeat.

This clever loop relies on Yahenni, Undying Partisan as your dedicated sacrifice outlet to continuously bin creatures like Nether Traitor. Every time Nether Traitor hits the graveyard, its built-in recursion triggers, allowing you to pay the single black mana to bring it right back to the battlefield—mana easily supplied by sacrificing the Treasure token generated along the way. Meanwhile, Kheru Goldkeeper and Chalk Outline act as your payoff engines, turning those cards leaving your graveyard into a ceaseless flood of Clues, Detectives, and Treasures.
