Loyal Retainers + Karmic Guide + Sakashima of a Thousand Faces + Phantom Train

Loyal Retainers

Karmic Guide

Sakashima of a Thousand Faces

Phantom Train

How it works

1. Activate Loyal Retainers by sacrificing it, returning Sakashima of a Thousand Faces from your graveyard to the battlefield as a copy of Karmic Guide.
2. When Sakashima of a Thousand Faces enters the battlefield, it triggers, returning Loyal Retainers from your graveyard to the battlefield.
3. Activate Phantom Train by sacrificing Sakashima of a Thousand Faces.
4. Repeat.

This elegant loop relies on Sakashima of a Thousand Faces entering the battlefield as a copy of Karmic Guide, allowing its enters-the-battlefield trigger to pull Loyal Retainers right back out of your graveyard. Since Sakashima acts as a Karmic Guide, you get the recursion engine going, while Phantom Train provides the crucial outlet to sacrifice Sakashima and fuel the repetition by turning it into a creature to be fed. Loyal Retainers then neatly caps off the cycle by sacrificing itself to bring Sakashima back, letting you endlessly repeat the process for limitless triggers and a massive Phantom Train.
