Body Launderer + Stunt Double + Clone + Ashnod's Altar

Body Launderer

Stunt Double

Clone

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Stunt Double, adding CC.
2. Stunt Double dies, triggering its second ability and Body Launderer's first ability.
3. Resolve the Stunt Double trigger, returning Clone from your graveyard to the battlefield as a copy of Body Launderer.
4. Resolve the Body Launderer trigger, causing it to connive.
5. Activate Ashnod's Altar by sacrificing Clone, adding CC.
6. Clone dies, triggering its second ability and Body Launderer's first ability.
7. Resolve the Clone trigger, returning Stunt Double from your graveyard to the battlefield as a copy of Body Launderer.
8. Resolve the Body Launderer trigger, causing it to connive.
9. Repeat.

This clever loop sets up an endless cycle of sacrifice and resurrection by letting two copy creatures continuously trade places. With Body Launderer already on the battlefield to provide the recursion engine, you cast either Stunt Double or Clone to enter as a copy of Body Launderer, then feed it to Ashnod's Altar for colorless mana. The resulting death trigger lets the dying copy pull the *other* copy straight out of your graveyard, which immediately re-enters as yet another Body Launderer to keep the chain alive. Every iteration also triggers Body Launderer's connive ability, churning through your deck for infinite card draw and stacking massive +1/+1 counters while generating endless mana and death triggers.
