do we really know if they are using that combo? because not everything you see in toy form means it's going to used in the show. as for that pic, you really cant tell if mach is working for chase because it's probably not have been shot yet, more like they are just setting up their characters where it's probably chase vs mach, like in shots with jam and ryugen on the same side and they were actually fighting each other in the shooting, they were just setting up their characters.
