This explosive engine relies on Silverskin Armor to turn our lead mechanic into an eligible target for Voltaic Construct's untap ability. Once the Armor bestows its artifact type, Howlsquad Heavy’s max speed ability—fueled by the Goblins it naturally pumps out—can be activated and endlessly reset. By using the generated red mana to pay for the Construct, you create an infinite loop that yields boundless red mana and endless untaps for all your artifact creatures.
