Orah, Skyclave Hierophant + Sister Hospitaller + Ancestor's Chosen + Phantom Train

Orah, Skyclave Hierophant

Sister Hospitaller

Ancestor's Chosen

Phantom Train

How it works

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

This clever graveyard loop is anchored by Orah, Skyclave Hierophant, whose triggered ability sets up a seamless exchange rate when a Cleric dies. By feeding Ancestor's Chosen and Sister Hospitaller to Phantom Train, you trigger Orah to continuously resurrect the pair while generating endless enter-the-battlefield and sacrifice triggers. Sister Hospitaller's entry brings back Ancestor's Chosen while fueling your life total, and Ancestor's Chosen rewards you with a massive life buffer based on your graveyard size. Meanwhile, Phantom Train happily accepts your sacrifices to grow infinitely larger with +1/+1 counters as it animates.
