Bastiodon

Bastiodon, although possessing gargantuan defenses and access to many useful support moves including Stealth Rock, Toxic, and Taunt, has always been overlooked for a position on UU teams due to its lackluster offenses. Thanks to moves such as Metal Burst and Torment, however, Bastiodon can present a serious threat while simultaneously contributing to the team. It's not a very reliable option considering its grave 4x weaknesses to Fighting- and Ground-type attacks and low Speed, but it can hold its own given the proper support.
