Body Launderer + Sister Hospitaller + Phyrexian Altar

Body Launderer

Sister Hospitaller

Phyrexian Altar

How it works

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

This loop creates an endless cycle of sacrifice and resurrection by trading back and forth between Body Launderer and Sister Hospitaller, all while Phyrexian Altar acts as the engine that turns each death into a mana source. Every time Sister Hospitaller re-enters the battlefield, her ability brings back Body Launderer while padding your life total, and sacrificing them right back to Phyrexian Altar triggers Body Launderer to pull her back out of the graveyard in return. The beauty of this pairing is how Body Launderer's connive trigger layers on top of the loop, letting you churn through your deck and filter your hand for free with every single iteration.
