Skarmory

Being one of the few Pokemon with access to both Brave Bird and Swords Dance, Skarmory is one of the best Gale Wings users in AAA. Possessing priority on Flying-type moves on its offensive set and considerable bulk on its defensive set in combination with a typing that provides it an immunity to Spikes and Toxic Spikes as well as a neutrality to Stealth Rock, Skarmory is also arguably the best Defog user in the metagame. In addition, its fantastic defensive typing and Defense stat allow it to both wall most opposing Gale Wings users and use many commonly used Pokemon in the metagame as setup fodder, further increasing both its defensive and offensive prowess. As if these traits weren't enough, Skarmory's ability to run both defensive and offensive sets often means the opponent cannot discern Skarmory's role on Team Preview, allowing it to potentially surprise the opponent. However, Skarmory's low HP and Special Defense stats prevent it from standing up to most special attackers, and it is easily eliminated by Magnet Pull Pokemon if it opts not to run a Shed Shell. Its low Attack stat among Gale Wings users also leaves it relatively weak before boosting, meaning it faces competition from Braviary, Staraptor, and Honchkrow, all of which can deal lots of damage right off the bat using a Choice Band. Finally, Skarmory lacks meaningful coverage moves outside of its Flying-type STAB moves, meaning it is easily walled by any Pokemon that resists Flying and has a means of fighting back.
