Zeraora

Zeraora is a potent offensive threat with its great Attack and ability to outspeed threats such as Blastoisinite and Red Orb Darkrai, Metagrossite Kartana, and Diancite Tapu Lele. A Pinsirite set gives it a strong Electric/Flying STAB type combination, allowing it to harass many common Pinsirite answers such as Skarmory, Pinsirite Magearna, Terrakion, and Cobalion. Pinsirite also boosts Zeraora's Attack and already blazing Speed to great levels, allowing it to check Pokemon like Kartana, Salamencite Noivern, and Pinsirite Magearna. Its STAB allows it to beat defensive Pokemon like Arceus-Water, Ho-Oh, and Sablenite Buzzwole, while Taunt allows Zeraora to get past Pokemon like Aggronite Buzzwole and support Arceus. Fake Out enables Zeraora to Mega Evolve safely and scout for the opposing side, as well as help for your team keep faster foes in check. However, due to its weakness to Stealth Rock after Mega Evolving, it can get worn down quickly. Zeraora also lacks recovery, which means that it is unable to repeatedly switch in on the Pokemon that it checks.
