This crafty loop hinges on the clever recursion clause of Traveling Plague, which automatically returns itself to the battlefield whenever its host bites the dust. By utilizing Goblin Bombardment as a convenient sacrifice outlet, you can repeatedly feed the enchanted creature to the fire and have Traveling Plague reattach itself right back to your board. Ghostly Dancers ties the whole engine together by turning every single one of those recurring enchantment entries into an endless supply of fresh 3/1 Spirit tokens—which simultaneously serve as the next sacrificial hosts and deal infinite damage to any target along the way.
