Buzzwole

Buzzwole's great physical bulk in conjunction with its rare defensive typing allows it to function as a blanket check on stall teams to many of the metagame's most dangerous physical attackers such as Kartana, Garchomp, and Tapu Bulu. Having a Bulk Up-boosted Buzzwole can be a win condition for stall teams, potentially sweeping bulky offensive teams in the late-game after they've been whittled down by Buzzwole's team. Buzzwole's movepool gives it access to a wide variety of coverage options such as Ice Punch for Gliscor and Landorus-T, allowing it to effectively utilize its high Attack stat. On the other hand, Buzzwole's mediocre special bulk leaves it susceptible to being KOed by strong special attacks such as Tapu Koko's Thunderbolt and Greninja's Hydro Pump after prior damage. Buzzwole's defensive typing also leaves it easily preyed upon by common attacking types in Flying, Fairy, and Psychic, and Buzzwole is easy to KO due to its poor Speed tier, so Pokemon like Mega Pinsir, Tapu Lele, and Clefable all force Buzzwole out with ease.
