Luminous Broodmoth + Pitiless Plunderer + Cult Conscript + Yahenni, Undying Partisan

Luminous Broodmoth

Pitiless Plunderer

Cult Conscript

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Cult Conscript.
2. When Cult Conscript dies, Luminous Broodmoth and Pitiless Plunderer trigger.
3. Resolve the Luminous Broodmoth trigger, returning Cult Conscript from your graveyard to the battlefield with a flying counter on it.
4. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
5. Activate Yahenni by sacrificing Cult Conscript.
6. When Cult Conscript dies, Pitiless Plunderer triggers, creating a Treasure token.
7. Resolve the Yahenni abilities from steps 1 and 5.
8. Activate the Treasures by tapping and sacrificing them, adding 1.
9. Activate Cult Conscript by paying 1, returning it from your graveyard to the battlefield.
10. Repeat.

This looping engine relies on the synergy between sacrifice outlets and resurrection mechanics to generate an endless cycle of death and rebirth. By feeding Cult Conscript to Yahenni, Undying Partisan, you trigger Luminous Broodmoth to return the Skeleton to the battlefield with a flying counter—giving it the flying it needs to bypass its own restriction on subsequent loops—while Pitiless Plunderer simultaneously mints a Treasure token to fund the action. Because Cult Conscript now bears a flying counter, it is no longer "without flying," meaning Luminous Broodmoth's initial trigger relies entirely on that first death, after which Pitiless Plunderer's mana generation seamlessly loops with Cult Conscript's own graveyard-recurrence ability.
