I support Metagross for C tier. Its understandable that it isn't what it was last generation, but it's still good. One of the main problems it has is four moveslot syndrome, but everyone is insisting on running stealth rock, here's a tip don't. With the following moves: Meteor Mash, Bullet Punch, Thunder Punch, Hammer Arm, Metagross is exceptional at what it does. Not only does it maintain an excellent offensive presence but it checks or counters the following: Dragonite Reuniclus Latias Latios Gengar Kyurem Kyurem-B Alakazam Terrakion Tornadus Tornadus-T Gyrados Mamoswine Blissey Chancey Aerodactyl Abomasnow All it needs is some investment in SpD and its good, this kind of checking is unheard of for most Pokemon.
