trample
3: urza's engine gains banding until end of turn. (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.)
