No one in a tour setting has used the cm set, while off the top of my head lvl 56 has used the support set in a couple of late round seasonal games. If you could offer a build that's consistent with the cm set I might change my opinion, but until one has been found, at this stage of the metagame it would save unnecessary work. I suggested unviable xerneas sets should be removed earlier in this thread, but as I can understand, the work for those analyses had already been done, so why bother removing them. However in this case, no one has made a solid build with the cm set and I don't even see it on ladder among new users, so what's the point of adding it? Whereas support has been used in a couple of tours, from my personal experience is extremely common on ladder, why not at least educate users on the best EV spreads and set for it?
