Aerodactyl

Aerodactyl's fantastic Speed tier allows it to outpace almost the entire metagame including Virizion and Sneasel, as well as Choice Scarf Hoopa and Emboar, making it a stellar revenge killer and late-game cleaner. It is only outsped by Accelgor and Choice Scarf users with a base Speed over 70 like Medicham. Its decent Attack stat coupled with a colorful offensive movepool and utility options like Stealth Rock allows it to mix up its moveset quite a bit. It is also the fastest viable Pursuit user in the tier, and its Rock typing allows it to check Fletchinder that try to switch out. Unfortunately, Aerodactyl has very mediocre bulk that prevents it from taking even neutral hits well. It is also weak to common offensive types like Rock, Steel, and Ice. Aerodactyl struggles against many physically defensive Pokemon, either due to their defensive typing resisting Aerodactyl's Rock STAB moves or because they can heal off the damage faster than Aerodactyl can deal it.
