Mandibuzz

Sablenite turns Mandibuzz into a wall that is able to withstand attacks from threatening offensive breakers such as Lunala, Kartana, and Primal Groudon, and access to Foul Play prevents passivity against physical threats. By virtue of its Dark typing and access to reliable recovery, it is one of the best defensive checks to Lunala and is thus mainly used as a dependable special wall. Magic Bounce, which is acquired upon Mega Evolving, grants Mandibuzz an immunity to status from defensive Pokemon such as support Arceus formes and defensive Primal Groudon. Furthermore, combined with access to Defog, it allows Mandibuzz to perform well in entry hazard control. With U-turn, it functions as a reliable slow pivot that can provide its teammates with free opportunities to switch in. However, a weakness to Stealth Rock can be detrimental to Mandibuzz’s ability to perform the aforementioned roles. Further, Mandibuzz is easily offensively pressured by most teams due to the abundance of Altarianite users such as Zygarde and Entei as well as the existence of Terrakion and Magearna. Boosted super effective coverage moves such as Ice Beam from Darkrai and Moonblast from Lunala can also overwhelm it. Finally, while it can't freely switch in, if Primal Groudon manages to preserve its HP, its Swords Dance and Eruption sets can muscle through Mandibuzz.
