Suncleanser + Luminous Broodmoth + Yahenni, Undying Partisan

Suncleanser

Luminous Broodmoth

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Suncleanser.
2. When Suncleanser dies, Luminous Broodmoth triggers, returning Suncleanser from your graveyard to the battlefield with a flying counter on it.
3. When Suncleanser enters the battlefield, it triggers, removing the flying counter from Suncleanser.
4. Resolve the Yahenni ability.
5. Repeat.
