Suncleanser + Luminous Broodmoth + Blasting Station

Suncleanser

Luminous Broodmoth

Blasting Station

How it works

1. Activate Blasting Station by tapping it and 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 and Blasting Station trigger.
4. Resolve the Suncleanser trigger, removing the flying counter from Suncleanser.
5. Resolve the Blasting Station trigger, untapping it.
6. Resolve the Blasting Station ability from step 1.
7. Repeat.

This clever loop turns Luminous Broodmoth into an engine for infinite damage by repeatedly sacrificing Suncleanser to Blasting Station. While the Broodmoth usually sends dying grounded creatures back to the battlefield with a pesky flying counter that would prevent further recursion, Suncleanser's clever entry trigger immediately strips that counter away the moment it returns. This ensures that every iteration is identical to the last, letting Blasting Station untap itself endlessly and continuously fire off damage until your opponents are reduced to ash.
