Rufflet

Rufflet has a high base 83 Attack stat which is boosted even further by Hustle, letting it hit very hard with its physical attacks. It's no slouch defensively, either, thanks to its 70 / 50 / 50 defenses and access to reliable recovery in Roost. Furthermore, its access to Superpower lets it hit Steel- and Rock-types hard, something most Flying-types struggle with. While Rufflet does boast incredible power with Hustle, the ability's downside is 80% accuracy on its physical moves, which can be frustrating, especially if you're trying to gain momentum with U-turn. In addition, Rufflet faces competition from Fletchling, Archen, and Doduo as an offensive Flying-type, and Vullaby as a defensive Flying-type, but it's able to effectively stand out from the flock thanks to its large raw power, bulk, and access to good coverage moves.
