Gallade

Gallade boasts an expansive movepool including Trick, Swords Dance, and Bulk Up, which makes it extremely versatile. Gallade's great type combination lets it beat Poison-, Steel-, and Fighting-types such as Venusaur, Registeel, and Hitmonlee, all of which are common in RarelyUsed. Furthermore, Gallade has access to Knock Off, which complements its dual STAB moves and hits Psychic-types such as Uxie and Sigilyph for heavy damage. Gallade's high-Base Power STAB moves are supported by its monstrous Attack stat, which turns it into a fearsome wallbreaker that can easily threaten defensively oriented teams. Gallade also sports a great Special Defense stat that allows it to switch into many special attacks comfortably. Moreover, Gallade's ability Justified gives it a free Attack boost when it is hit by a Dark-type attack. Unfortunately, Gallade's subpar physical bulk coupled with its low base HP makes it very physically frail, especially after a Defense drop from Close Combat. Its average Speed leaves it vulnerable to revenge killers and priority users such as Flygon and Fletchinder. Finally, in a tier saturated with Fighting-types, Gallade faces tough competition from the likes of Medicham, Virizion, and Hitmonlee.
