Zacian-C works well on nearly every offensive and balanced team structure. In particular, Swords Dance Zacian-C is excellent at taking out or severely weakening defensive threats such as Skarmory, Corviknight, and Necrozma-DM. As such, offensive Pokemon that appreciate Zacian-C's ability to break down defensive cores work well as partners; examples include Excadrill, Kyurem-B, and Dragon Dance Necrozma-DM. The best check to Zacian-C is Quagsire, as it ignores Zacian-C's Attack boosts. Therefore, Gothitelle deserves a special mention, as it's able to trap and KO Quagsire with relative ease. For Shed Shell Quagsire, entry hazard damage is critical, allowing Adamant Zacian-C to 2HKO it with Play Rough. Skarmory, Ferrothorn, and Eternatus are good entry hazard setters. Mew and Grimmsnarl are excellent teammates for offensive teams, as their respective entry hazard and dual screens support lets Zacian-C sweep more easily. Switch-ins to opposing Zacian-C such as Quagsire, Necrozma-DM, Skarmory, and Corviknight are greatly appreciated, as Ditto is able to copy Zacian-C's boosts and potentially sweep.
