Orah, Skyclave Hierophant + Sister Hospitaller + Ancestor's Chosen + Umbral Collar Zealot

Orah, Skyclave Hierophant

Sister Hospitaller

Ancestor's Chosen

Umbral Collar Zealot

How it works

1. Activate Umbral Collar Zealot 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 Umbral Collar Zealot ability.
6. Activate Umbral Collar Zealot 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 Umbral Collar Zealot ability.
9. Repeat.

This clever loop turns your graveyard into a revolving door of life and holy recursion, powered by Orah, Skyclave Hierophant acting as the engine that catches your falling Clerics. You begin by using Umbral Collar Zealot to sacrifice Ancestor's Chosen, whose demise triggers Orah to pluck Sister Hospitaller straight from your graveyard. When Sister Hospitaller hits the battlefield, her own enter-the-battlefield ability triggers to bring Ancestor's Chosen right back, setting up an endless cycle that endlessly pads your life total with the massive lifegain from Ancestor's Chosen and Sister Hospitaller while cycling through your deck with the zealot's surveil.
