Loyal Retainers + Karmic Guide + Umbral Collar Zealot + Moritte of the Frost

Loyal Retainers

Karmic Guide

Umbral Collar Zealot

Moritte of the Frost

How it works

1. Activate Loyal Retainers by sacrificing it, returning Moritte of the Frost from your graveyard to the battlefield as a copy of Karmic Guide.
2. When Moritte of the Frost enters the battlefield, it triggers, returning Loyal Retainers from your graveyard to the battlefield.
3. Activate Umbral Collar Zealot by sacrificing Moritte of the Frost.
4. Repeat.

This ingenious loop turns a graveyard into an endless revolving door by leveraging Moritte of the Frost's unique ability to enter the battlefield as a copy of Karmic Guide. When Moritte enters, its copied triggered ability reaches into the graveyard to pull back Loyal Retainers, setting up the exact fuel needed to sacrifice Loyal Retainers and restart the whole cycle. Meanwhile, Umbral Collar Zealot provides the necessary sacrifice outlet to bin the Karmic Guide-copy whenever you need to repeat the process, while simultaneously filtering your draws with its surveil ability.
