This clever loop turns Arid Archway's self-bouncing drawback into a perpetual motion machine, fueled by Patron of the Moon's ability to effortlessly drop lands back onto the battlefield for just one mana. Every time Arid Archway enters, its own trigger dutifully bounces it right back to your hand so it can be replayed, creating an endless cycle of land drops. Meanwhile, Nissa, Resurgent Animist watches each of these entries to generate a mana of any color and dig through your library for Elves and Elementals, letting you churn through your deck while easily paying for the repeated activations.
