The biggest problem that I see is that you don't have one physical attacker, if Someone were to come in with a sp. tank, you would be finished. Metagross should be ev trained in attack not sp. attack. Try something like this: Metagross trained in attack and speed, holding light clay with the moves light screen, zen headbutt, meteor mash, and earthquake/hammer arm. Maybe get rid of kindra for a physical attacker, so you dont get annihilated by a sp.tank or something.
