Nether Traitor + Kheru Goldkeeper + Yahenni, Undying Partisan + Quintorius, History Chaser

Nether Traitor

Kheru Goldkeeper

Yahenni, Undying Partisan

Quintorius, History Chaser

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 Quintorius, History Chaser triggers, creating a Treasure token and creature token.
5. Resolve the Yahenni ability.
6. Activate the Treasure by tapping and sacrificing it, adding .
7. Repeat.

This crafty loop turns the graveyard into a revolving door, powered by Yahenni, Undying Partisan sacrificing Nether Traitor over and over. Each time Nether Traitor hits the graveyard, its own self-recurring trigger lets you pay black mana to bring it right back, a cost easily paid by tapping and sacrificing the Treasure token generated by Kheru Goldkeeper. Meanwhile, Quintorius, History Chaser keeps watch over the yard, triggering alongside Kheru Goldkeeper whenever cards leave it to flood your board with a steady stream of Spirit tokens.
