Body Launderer + Karmic Guide + Thermopod

Body Launderer

Karmic Guide

Thermopod

How it works

1. Activate Thermopod by sacrificing Karmic Guide.
2. When Karmic Guide dies, Body Launderer's first ability triggers, causing Body Launderer to connive.
3. Activate Thermopod by sacrificing Body Launderer.
4. When Body Launderer dies, its second ability triggers, returning Karmic Guide from your graveyard to the battlefield.
5. When Karmic Guide enters, it triggers, returning Body Launderer from your graveyard to the battlefield.
6. Repeat.

This clever loop turns a graveyard recursion engine into an infinite well of red mana and card filtering by constantly swapping key pieces back and forth. You start by using Thermopod to sacrifice Karmic Guide, which lets Body Launderer trigger its connive ability to churn through your deck while Body Launderer itself is subsequently fed to the same Thermopod. Once Body Launderer hits the graveyard, its death trigger brings back Karmic Guide, and the returning Karmic Guide immediately loops right back around to resurrect Body Launderer.
