Humility

Few cards in the game's history have generated as many disputed board states or as much judge education as this one, and the reason is layers: the rules machinery that decides which continuous effects apply in what order. The effect is total and symmetrical, turning every creature on the board (yours included) into a vanilla 1/1, which leaves the card stranded in tension between control answer and self-sabotage. It sets base power and toughness, but a creature that gains a static buff from a later-applied effect can still grow, and abilities granted by other continuous effects survive in ways that produce some of the thorniest interactions ever printed. A creature wearing equipment is the textbook case: the equipment's bonus may stick even as the creature's printed abilities vanish. That tension is exactly what makes the card interesting. It punishes ability-dense decks, neuters keyword soup and activated engines wholesale, and asks its own pilot to win with something that does not care about being a 1/1: burn, noncreature threats, or a buff placed in the right layer. It demands more rules literacy to deploy correctly than nearly any enchantment, and rewards it with as complete a lock on a creature-based opponent as white can offer. This is less a removal spell than a rule rewrite, and the price of casting it is that you have to understand the rules better than the person across the table.
