Pidgeot

Because of its consistently low stats barring Speed and small movepool, Pidgeot is an unviable and completely outclassed Flying-type in PU. Offensively, Pidgeot is outclassed by other Flying-types like Swanna, Scyther, Oricorio-E, and Dodrio in particular, which can hit harder and has more useful coverage with boosting moves like Swords Dance. Additionally, its mediocre typing and stats offer nothing defensively over Articuno, Altaria, or other Defog users like Skuntank. Pidgeot often doesn't force much out, while other Defog users like Swanna and Skuntank can use Defog while the opponent is switching.
