Imperial Legion Cavalry

Haste, 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 among any of the creatures it's being blocked by or is blocking.)
Battalion - Whenever Imperial Legion Cavalry
and at least two other creatures attack, you may pay {w}. If you do, create a 2/2 white Knight creature token with banding.
