Infernal Vessel + Luminous Broodmoth + Phantom Train

Infernal Vessel

Luminous Broodmoth

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Infernal Vessel.
2. When Infernal Vessel dies, it triggers, returning itself from your graveyard to the battlefield as a Demon in addition to its other types.
3. Resolve the Phantom Train ability.
4. Activate Phantom Train by sacrificing Infernal Vessel.
5. When Infernal Vessel dies, Luminous Broodmoth triggers, returning Infernal Vessel from your graveyard to the battlefield with a flying counter on it.
6. Resolve the Phantom Train ability.
7. Repeat.

This clever loop turns Infernal Vessel into a perpetual sacrifice engine by exploiting how its own resurrection clause interacts with Luminous Broodmoth. Because Infernal Vessel isn't a Demon the first time it dies, its native trigger brings it back as a Demon, while Phantom Train provides the convenient outlet to sacrifice it repeatedly. Once it returns as a Demon, Luminous Broodmoth steps in to catch subsequent deaths—returning it with a flying counter—which keeps the cycle churning indefinitely to generate infinite deaths, sacrifices, and massive power for Phantom Train.
