Cult of the Waxing Moon

A green payoff built around the flip itself, not the cast. The trigger is narrower than it reads: it fires only when a permanent you control transforms into a non-Human creature, which on the day-into-night side means the back faces of werewolves, the awakened halves of certain double-faced lands, and other flip-to-monster permanents. Green shares werewolf duty with red, so the flippers to feed this exist; what the card asks for is volume of transform triggers, not just a pile of green creatures. Every time the moon comes out, so does a 2/2 Wolf, turning the rhythm of werewolves flipping back and forth into a token engine that quietly widens the board. The discipline is in the word "transforms": casting a double-faced creature does nothing, and a static permanent that simply is a non-Human does nothing; the card rewards the act of changing forms, which puts a premium on decks that can reliably trip the night side and trip it again. The 5/4 body is the tell that the trigger was never going to carry the card alone; it has to threaten on its own while the engine assembles around it. It belongs to that small family of tribal-adjacent payoffs whose output scales entirely with how committed a deck is to one archetypal mechanic: generous when the board is full of flippers, and when it is not, a plain green beater whose ability simply sits idle, waiting for a transform that never comes.
