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.)  Even after the wall was breached in half a dozen places, the Phalanxes fought on, standing solidly against the onrushing raiders. Disciplined and dedicated, they held their ranks to the end, even in the face of tremendous losses.
