This loop is an exquisite dance of recycling and resource conversion, turning energy and artifacts into an unstoppable engine. Chthonian Nightmare acts as the primary catalyst, using its initial three energy counters to sacrifice creatures and leap back to your hand while pulling others from the graveyard. Meanwhile, Patron of the Arts provides the vital fuel by spitting out a Treasure token whenever it enters or leaves, which can then be sacrificed for mana. Because Jet Medallion reduces the casting cost of black spells, recasting Chthonian Nightmare becomes entirely self-sustaining on a single black mana generated by the Treasures, allowing you to cycle through your graveyard indefinitely.
