Ampharos has his stats in special attack, hp, and defense. Ampharos also has a modest nature to further increase it's special attack. It holds a sitrus berry to heal at half health. First, you realy want to use cotton guard. This bolsters your defence by 2.5 times making it hard for earthquake to KO. Then, if a ground type isn't on the field, use charge beam to get a special attack rise. Finally use thunderbolt or dragon pulse for high damage. Dragon pulse also really helps against garchomps.
