This clever brew achieves an instant victory by bending the rules of the color pie entirely from the opening turn. With Leyline of the Guildpact already on the battlefield from your opening hand, your lands instantly become every basic land type, easily satisfying half of Coalition Victory's demanding requirements. At the same time, that very same Leyline paints every nonland permanent you control in all five colors, ensuring your creatures instantly cover the remaining color requirements to immediately resolve Coalition Victory and claim the win.
