Perigee Beckoner + Karmic Guide + Phantom Train

Perigee Beckoner

Karmic Guide

Phantom Train

How it works

1. Cast Perigee Beckoner for its warp cost by paying 1.
2. When Perigee Beckoner enters, it triggers, targeting Karmic Guide.
3. Activate Phantom Train by sacrificing Perigee Beckoner.
4. Activate Phantom Train by sacrificing Karmic Guide.
5. When Karmic Guide dies, it triggers, returning itself from your graveyard to the battlefield tapped.
6. When Karmic Guide enters, it triggers, returning Perigee Beckoner from your graveyard to the battlefield.
7. When Perigee Beckoner enters, it triggers, targeting Karmic Guide.
8. Resolve the Phantom Train ability from step 4.
9. Repeat from step 3.

This ingenious loop harnesses Phantom Train as a sacrifice outlet to continuously feed your graveyard and fuel its own ability with endless +1/+1 counters. By casting Perigee Beckoner for its warp cost, its entry trigger temporarily bestows a life-after-death effect onto Karmic Guide, ensuring that whenever Karmic Guide perishes, it immediately returns itself to the battlefield tapped. That revival triggers Karmic Guide's own enter-the-battlefield ability to pull Perigee Beckoner right back out of the graveyard, resetting the cycle and generating infinite creature sacrifices, entry triggers, and death triggers in the process.
