Karmic Guide + Body Double + Blasting Station

Karmic Guide

Body Double

Blasting Station

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 and Blasting Station triggers, with the Body Double trigger targeting Karmic Guide.
3. Resolve the Blasting Station trigger, untapping it.
4. Holding priority, activate Blasting Station by tapping it and sacrificing Body Double.
5. Resolve the Body Double trigger, returning Karmic Guide from your graveyard to the battlefield.
6. When Karmic Guide enters the battlefield, it and Blasting Station trigger, with the Karmic Guide trigger targeting Body Double.
7. Resolve the Blasting Station trigger, untapping it.
8. Holding priority, activate Blasting Station by tapping it and sacrificing Karmic Guide.
9. Resolve the Karmic Guide trigger, returning Body Double from your graveyard to the battlefield as a copy of Karmic Guide.
10. Repeat from step 2.

This infinite loop is a masterclass in recycling, utilizing Body Double to enter as a copy of Karmic Guide and immediately trigger its ability to pull the real Karmic Guide straight out of your graveyard. Meanwhile, Blasting Station acts as the ultimate engine, using its passive untap trigger whenever a creature enters to ready itself for another sacrifice. By looping these two creatures back and forth between the battlefield and the graveyard, Blasting Station can be repeatedly tapped to sacrifice them and continuously ping any target for infinite damage.
