Mass Mutiny

Threaten effects normally borrow one creature, fling it across the table, and call it a turn; this scales that template to the whole pod, peeling the best blocker off every opponent at once. That multiplication is what makes it a swing card rather than a removal-adjacent tempo play: in a four-player game it can strip the table of its defenses and hand you a hasty alpha strike, and it pairs naturally with sacrifice outlets that convert the borrowed bodies into permanent value before they snap back at end of turn. The "up to one" wording is the polite half of the design, letting you skip an opponent who controls nothing worth taking rather than wasting the spell, but the real cost is structural: it untaps and grants haste to creatures it does not let you keep, so the entire payoff lives inside a single combat step. Miss the attack window and you have handed your opponents nothing while spending five mana. It is the multiplayer answer to a problem single-borrow effects never had to solve, namely that grabbing one creature in a game with three opponents is a rounding error, and it leans hard on the asymmetry of an aristocrats or sacrifice shell to turn a one-turn loan into a closing move.
