Body Launderer + Sister Hospitaller + Phantom Train

Body Launderer

Sister Hospitaller

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Sister Hospitaller.
2. When Sister Hospitaller dies, Body Launderer's first ability triggers, causing Body Launderer to connive.
3. Resolve the Phantom Train ability.
4. Activate Phantom Train 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 Phantom Train ability.
8. Repeat.

This clever loop transforms Phantom Train into an engine of endless rebirth by using its ability to sacrifice your creatures on demand. Every time Sister Hospitaller hits the graveyard, Phantom Train lets you feed Body Launderer to the locomotive, whose own death trigger then reaches back into the graveyard to pull Sister Hospitaller straight back to the battlefield. Meanwhile, Body Launderer benefits from its own passive connive triggers along the way, while Sister Hospitaller's entry ability continuously resurrects Body Launderer while stacking up life.
