Sister Hospitaller + Yahenni, Undying Partisan + Faceless Butcher

Sister Hospitaller

Yahenni, Undying Partisan

Faceless Butcher

How it works

1. Cast Faceless Butcher by paying its mana cost.
2. When Faceless Butcher enters, its first ability triggers, exiling Sister Hospitaller.
3. Activate Yahenni by sacrificing Faceless Butcher.
4. When Faceless Butcher dies, its second ability triggers, returning Sister Hospitaller from exile to the battlefield.
5. When Sister Hospitaller enters, it triggers, returning Faceless Butcher from your graveyard to the battlefield.
6. When Faceless Butcher enters, its first ability triggers, exiling Sister Hospitaller.
7. Resolve the Yahenni ability.
8. Repeat from step 3.

This delightful little loop sets up an endless cycle of revival and sacrifice by bouncing Faceless Butcher and Sister Hospitaller back and forth infinitely. Whenever the Butcher enters to exile your Sister Hospitaller, Yahenni, Undying Partisan steps in as the willing executioner, sacrificing the Butcher to trigger its own protection and send the Butcher back to the graveyard. That death immediately releases the Sister Hospitaller from exile, allowing her entry trigger to pluck the Butcher right back out of the graveyard and restart the whole chain. The result is an endless cascade of enters-the-battlefield and leaves-the-battlefield triggers, fueling continuous life gain from the Sister while growing Yahenni into an unstoppable horror.
