Phalanx Barracks

{t}: Add {w}
At the beginning of each combat, you may pay {1}. If you do, target creature gets banding (Any creatures with banding, and up to one without, can
attack in a band. Bands are blocked as a group. If
any creatures with banding you control are blocking
or being blocked by a creature, you divide that
creature's combat damage, not its controller, among
any of the creatures it's being blocked by or is
blocking.)
