Ulvenwald Mystics // Ulvenwald Primordials

Werewolves run on a shared dial, and this one hands that dial to the whole table. The 3/3 day side flips to its bigger, regenerating back only after a turn where nobody casts a spell, so the green deck holding it gets paid for doing nothing: pass with mana up, decline to commit, and let the pack thicken. The reward for that restraint is the night form's single-mana regeneration, a blocker that green mana can keep alive through removal and combat. The flip-back clause is what keeps the trade honest: any player casting two or more spells in a turn drags the creature back to its human shell, which means every opponent holds a clean lever to undo the transformation just by being busy. Strength here is gated by tempo rather than by mana or stats, favoring a deck that does its work at instant speed or on land drops instead of leaning on a sorcery-speed curve. It is an early example of the werewolf mechanic's central bet: a board state that swings on the question of who is willing to stop casting, with the flip cost falling on whoever wants the bigger body to either appear or go away.
