This clever loop turns your noncreature artifacts into a massive mana engine by leveraging Toph, the First Metalbender's static ability, which transforms all of your nontoken artifacts into lands. With that foundation set, Everflowing Chalice can be cast with enough multikicker charges to produce more than enough mana to feed Candelabra of Tawnos. By tapping the Chalice for substantial colorless mana, you then use the Candelabra's ability to untap both artifacts—which are now legally recognized as lands thanks to Toph—allowing you to easily net infinite colorless mana and infinite untaps.
