Mega Manectric helps to check Flying-types and Water-types which trouble Volcarona by threatening them with a Super Effective Thunderbolt. In return, Volcarona can take on Grass-types, bulky Psychics, Clefable and Mega Sableye which Mega Manectric struggles against. Starmie is added to the core to provide Rapid Spin support since Volcarona hates losing 50% of its health while Mega Manectric wants to pivot around more freely. It also helps to check Heatran, Gliscor, Hippowdon and Dragon-type check. In return, Volcarona and Mega Manectric easily deals with Slowbro, Mega Scizor and Ferrothorn.
