Here's a suggestions for Metagross move-set form Metagross master/lover ;D :
Metagross@Leftovers[for staying longer] Or Lum berry [to heal status problems and with clear body, it's stats won't get lowered, so what will you do to annoy him XD]
Trait: Clear Body[there isn't any other options, and even if there was this is the best]
Nature: Adamant [+ATK, -SP.ATK]
Meteor Mash [a strong steel move that also gains a STAB bonus]
Earthquake[to cover fire, and many other types]
RockSlide [for Charizard/Ho-Oh/Skarmory [yea it has good def, but Metagross has goos attack, so one or two RS will KO skarm]
Aerial Ace[for earthquaking fighting types]
Well it's good for me, and it didn't fail me, anyways there are other sets like the one above but insted of RS agility for it's speed problem, also there is this:to tell you the truth, this isn't a very good set. if your gonna put all attacking moves on him, at least give him a choice band. AA isn't needed as STABed MM does more damage to fighters. RS isn't that good in-game because it's mainly for Zapdos.
Liechi>SalacDodrio @ Salac Berry
Trait: Early Bird
Adamant Nature (+Atk, -SAtk)
