Mienshao

Mienshao is a good fast pivot due to its access to U-turn and Knock Off in conjunction with Regenerator and an Assault Vest, allowing it to constantly pivot in and chip foes throughout a game. Furthermore, its high Speed lets it outspeed metagame staples such as Hydreigon, Celebi, and Nihilego, which greatly bolsters its ability as a pivot, and its pure Fighting typing enables Mienshao to check some of the tier's key threats in Hydreigon and Kyurem. Mienshao can also switch into other special attackers more easily due to its resistance to Stealth Rock and its increased special bulk from an Assault Vest. However, its typing also leaves it vulnerable to several key attacking types in Fairy, Flying, and Psychic, and it struggles with foes such as Mega Altaria, Moltres, and Latias as a result. While Mienshao may be able to switch into some special attacks due to its Assault Vest, it has minimal physical bulk, which makes it vulnerable to priority moves from Scizor, Mamoswine, and Crawdaunt and faster physical attackers like Terrakion and Zeraora.
