Havengul Lich + Shambling Ghast + Mirror Room // Fractured Realm + Phantom Train

Havengul Lich

Shambling Ghast

Mirror Room // Fractured Realm

Phantom Train

How it works

1. Activate Havengul Lich by paying 1, allowing you to cast Shambling Ghast card from your graveyard this turn.
2. Cast Shambling Ghast from your graveyard by paying .
3. Activate Phantom Train by sacrificing Shambling Ghast.
4. When Shambling Ghast dies, it triggers twice, creating two Treasure tokens.
5. Resolve the Phantom Train ability.
6. Activate the Treasures by tapping and sacrificing them, adding 1
7. Repeat.

This looping engine relies on Havengul Lich to repeatedly resurrect Shambling Ghast from your graveyard by continuously paying its activation cost. Each time Shambling Ghast is sacrificed to fuel Phantom Train's ability, Mirror Room // Fractured Realm doubles the resulting death triggers so you profit extra mana from the generated Treasure tokens. This surplus of mana and disposable fodder allows you to infinitely feed Phantom Train, pumping it full of +1/+1 counters while generating endless loops of artifact and creature movement.
