This engine loops by feeding Clues into Arcbound Ravager's sacrifice outlet, utilizing the clever overlapping triggers of Lonis, Genetics Expert and Piper Wright, Publick Reporter. Whenever you sacrifice a Clue, both Lonis and Piper Wright trigger to pump your creatures, which in turn causes Lonis to investigate and replace the sacrificed artifact with a fresh Clue. This creates a self-sustaining loop that continuously builds an unstoppable army of massive creatures.
