This engine turns a relentless spirit into a self-feeding sacrifice loop by exploiting a clever rules interaction with persist. When you sacrifice Restless Apparition to Viscera Seer, persist normally would return it with a -1/-1 counter that prevents the loop from repeating. However, Melira, Sylvok Outcast's static ability completely prevents -1/-1 counters from being placed on your creatures, allowing the Apparition to return completely clean every single time. By continuously cycling the creature back and forth, you generate an endless stream of sacrifice and death triggers while using Viscera Seer to manipulate your library until you find your winning card.
