Luminous Broodmoth + Viscera Seer

Luminous Broodmoth

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing the persist or undying creature.
2. When the creature dies, its persist or undying ability triggers if it doesn't have a -1/-1 counter or +1/+1 counter on it respectively, and Luminous Broodmoth triggers if the creature didn't have flying.
3. Resolve the persist or undying trigger, if applicable, returning the creature from your graveyard to the battlefield with either a -1/-1 counter or a +1/+1 counter on it.
4. Resolve the Luminous Broodmoth trigger, if applicable, returning the creature from your graveyard to the battlefield with a flying counter on it if the creature is still in your graveyard.
5. Resolve the Viscera Seer ability.
6. Repeat.
