Rattleblaze Scarecrow + Luminous Broodmoth + Krark-Clan Ironworks

Rattleblaze Scarecrow

Luminous Broodmoth

Krark-Clan Ironworks

How it works

1. Activate Krark-Clan Ironworks by sacrificing Rattleblaze Scarecrow, adding CC.
2. When Rattleblaze Scarecrow dies, its persist ability triggers if it didn't have a -1/-1 counter, and Luminous Broodmoth triggers if Rattleblaze Scarecrow didn't have flying.
3. Resolve the persist trigger, if applicable, returning Rattleblaze Scarecrow from your graveyard to the battlefield with either a -1/-1 counter on it.
4. Resolve the Luminous Broodmoth trigger, if applicable, returning Rattleblaze Scarecrow from your graveyard to the battlefield with a flying counter on it if Rattleblaze Scarecrow is still in your graveyard.
5. Repeat.
