I was on serebii, and though the people on this site told me Metagross could breed with ditto, serebii said it couldnt being in group x. So who is right?
P.S. The link is(to the serebii page I was looking at) http://www.serebii.net/pokemon_advance/egg-group.shtml
It can breed, but only with ditto. only legendaries (except manaphy) and baby pokemon are unable to breed.
