Hoopa

Hoopa's good offensive typing, ability to outspeed most defensive Pokemon, and massive Special Attack stat give it the tools to seriously bust holes in opposing teams. This is bolstered by its access to Nasty Plot and All-Out Pummeling, which further increases Hoopa's wallbreaking potential and allows it to muscle past would-be checks such as Alolan Muk and Blissey with ease after some mild chip damage. Hoopa also boasts impressive 80 / 130 special bulk, allowing it to take on the likes of Latias and Suicune. However, Hoopa's greatest strength, its Ghost / Psychic typing, is also its greatest weakness, giving it a 4x weakness to Pursuit, thus limiting its matchup versus offensively inclined teams. In addition, Hoopa's poor Speed and Defense stats leave it forced out by common physical attackers, such as Cobalion and Infernape. Finally, Hoopa faces stiff competition as an offensive Ghost-type from the likes of Mimikyu and Gengar, which offer better Speed and utility than Hoopa. Other Psychic-types like Celebi, Latias, and Starmie also offer better Speed and utility and less vulnerability to Pursuit trapping. Hoopa's ability, Magician, also is useless in every situation.
