This grim loop transforms a simple sacrifice outlet into an engine of endless rebirth, centered around Shilgengar, Sire of Famine turning your fallen minions into Blood tokens. Lingering Tormentor is the ideal sacrificial lamb here, as its persist ability normally limits its returns by accumulating -1/-1 counters—a restriction entirely bypassed by Vizier of Remedies reducing those incoming counters to zero. Because the Tormentor comes back completely clean every single time, you can sacrifice it to Shilgengar over and over to generate an endless horde of Blood tokens, triggering infinite entry, leave-the-battlefield, and death events along the way.
