Body Launderer + Sister Hospitaller + Yahenni, Undying Partisan

Body Launderer

Sister Hospitaller

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Sister Hospitaller.
2. When Sister Hospitaller dies, Body Launderer's first ability triggers, causing Body Launderer to connive.
3. Resolve the Yahenni ability.
4. Activate Yahenni by sacrificing Body Launderer.
5. When Body Launderer dies, its second ability triggers, returning Sister Hospitaller from your graveyard to the battlefield.
6. When Sister Hospitaller enters, it triggers, returning Body Launderer from your graveyard to the battlefield and causing you to gain 4 life.
7. Resolve the Yahenni ability.
8. Repeat.

This loop operates as an endless cycle of sacrifice and resurrection between Body Launderer and Sister Hospitaller, fueled by Yahenni, Undying Partisan as the outlet. When you sacrifice Sister Hospitaller to Yahenni, Body Launderer triggers to connive, filtering your hand while growing larger. Sacrificing Body Launderer next triggers its own death ability to bring back Sister Hospitaller, whose entry ability immediately returns Body Launderer to the battlefield and pads your life total. Repeating this cycle yields a staggering storm of death triggers, enters-the-battlefield effects, and card looting without ever running out of fuel.
