Multiplayer politics usually lives in a card's text as a suggestion: a group-hug enticement, a monarch to fight over, a Goad that redirects one creature. This one legislates the whole table. By fixing every player's legal attack to a single direction around the table, it converts the free-for-all into a wheel, where each seat can only swing at the neighbor ahead of it (and that neighbor's planeswalkers) and can only be swung at by the neighbor behind. The result is a geometry puzzle rather than a threat: it does not stop damage, it channels it, and the person choosing left or right on entry gets to decide who sits downstream of whom. That single choice is the entire design, and the reason the card matters more as a table-state artifact than as a body. The 1/5 flyer with defender is almost incidental scaffolding; it exists to hold the enters-choice in play as a permanent that opponents must remove to dissolve the arrangement. Because the restriction applies symmetrically to its own controller, it is not a shield so much as a rule change everyone now lives under, rewarding the player who read the board's political map before locking the direction. Few commanders alter combat as a shared system rather than as a personal advantage; this one turns the defining structure of multiplayer, who can hit whom, into a lever you pull once and everyone else has to route around.
