This clever assembly transforms Marvin, Murderous Mimic into a self-contained mana engine by borrowing the best traits from your other artifacts. With Palladium Myr on the board, Marvin gains the ability to tap for two colorless mana, while Pili-Pala supplies the untap mechanic—further fueled by its own untap symbol ability that converts that mana and untaps Marvin for a repeat performance. Because Marvin copies these abilities without needing them to be distinct creatures with the same name, this loop easily generates infinite colored and colorless mana to power the rest of your deck.
