Orah, Skyclave Hierophant + Sister Hospitaller + Valiant Changeling + Phantom Train

Orah, Skyclave Hierophant

Sister Hospitaller

Valiant Changeling

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Valiant Changeling.
2. When Valiant Changeling dies, Orah triggers, returning Sister Hospitaller from your graveyard to the battlefield.
3. When Sister Hospitaller enters, it triggers, returning Valiant Changeling from your graveyard to the battlefield and causing you to gain 7 life.
4. Resolve the Phantom Train ability.
5. Activate Phantom Train by sacrificing Sister Hospitaller.
6. When Sister Hospitaller dies, Orah triggers, allowing you to return a Cleric with mana value 5 or less from your graveyard to the battlefield.
7. Resolve the Phantom Train ability.
8. Repeat.

This clever loop turns Phantom Train into a continuous sacrifice engine that feeds on its own passengers. Orah, Skyclave Hierophant sits at the center as the ultimate director of the graveyard, leveraging its triggered ability to catch each Cleric as it falls. When Valiant Changeling hits the graveyard as the train's fuel, Orah's trigger reaches down to resurrect Sister Hospitaller, whose entrance trigger immediately brings the changeling right back alongside a healthy boost of life. As you pivot to sacrificing Sister Hospitaller to the Phantom Train, Orah's higher mana-value threshold catches the chaplain in turn, keeping the cycle spinning indefinitely.
