Karmic Guide + Body Double + Altar of Dementia

Karmic Guide

Body Double

Altar of Dementia

How it works

1. Cast Body Double by paying 4, choosing to have it enter the battlefield as a copy of Karmic Guide.
2. When Body Double enters the battlefield, it triggers, targeting Karmic Guide.
3. Holding priority, activate Altar of Dementia by sacrificing Body Double.
4. Resolve the Body Double trigger, returning Karmic Guide from your graveyard to the battlefield.
5. When Karmic Guide enters the battlefield, it triggers, targeting Body Double.
6. Holding priority, activate Altar of Dementia by sacrificing Karmic Guide.
7. Resolve the Karmic Guide trigger, returning Body Double from your graveyard to the battlefield as a copy of Karmic Guide.
8. Repeat from step 2.

This elegant loop relies on a clever continuous exchange of resurrection between Body Double and Karmic Guide. By having Body Double enter the battlefield as a copy of Karmic Guide, it triggers its ability to pull the real Karmic Guide straight out of your graveyard, setting up a perpetual cycle where each creature continuously fishes the other back whenever they hit the dirt. Meanwhile, Altar of Dementia provides the crucial sacrifice outlet that bridges the gap, weaponizing this endless cycle of life and death to mill your opponents out completely.
