This clever loop transforms Battered Golem into a veritable token factory by enchanting it with Elemental Mastery so that tapping it yields a surge of hasty Elementals. Because those creatures arriving—along with the replacement effect from Peregrin Took—simultaneously flood the board with new artifact tokens, Battered Golem's static-triggered ability constantly sees something new entering and triggers to untap itself. Once you have enough pieces in motion, Peregrin Took's activated ability also lets you cash in those extra snacks for infinite card draw.
