Rowlet

Rowlet's terrible stats do not let it perform as an effective sweeper or wallbreaker; it's too slow, weak, and frail to take advantage of its useful offensive Grass / Flying typing and its access to Swords Dance. Its typing, while decent offensively, is extremely weak defensively and does not allow Rowlet to set up on almost any common Pokemon in LC. As such, Rowlet finds itself both offensively and defensively outclassed by Flying-types such as Vullaby and Rufflet and Grass-types like Snivy and Foongus, leaving it with no viable niche to justify ever putting it on a team.
