Swellow

Normal

Swellow has access to a strong STAB attack in Boomburst, which it can freely spam for massive damage even against Ghost-types thanks to its useful ability in Scrappy. Despite Swellow's average Special Attack stat, it's still able to deal great damage with Boomburst. Furthermore, Swellow's impressive Speed stat allows it to outpace a variety of threats such as Keldeo, Latios, and non-Choice Scarf users such as Gengar and Greninja. Swellow's Flying typing allows it to come in on a resisted Bug- or Grass-type attack while also granting it immunity to Ground-type moves. Swellow also has a good coverage move in Heat Wave, which is great for checking Steel-types. Unfortunately, Swellow's lackluster bulk makes it easier to be KOed by priority and revenge killed by Choice Scarf users. Swellow's special movepool is very limited, leaving it with weak coverage options such as Hidden Power. Swellow's Flying typing also comes with a cost in giving it a Stealth Rock weakness, limiting its opportunities to switch in and use U-turn when needed. With average offenses, Swellow requires team support to effectively secure KOs, as it needs foes to be weakened by its teammates and entry hazards to clean effectively. It also faces huge competition from Mega Pidgeot, which fits on Normal teams more easily, is also able to outspeed threats under base 121 Speed, has a better STAB move in Hurricane, and comes with better bulk, making it less prone to being revenge killed.
