Stunky

With access to Pursuit and Sucker Punch, Stunky is able to trap and remove strong special attackers like Gastly and Abra very easily. Stunky also is able to carve its own niche as a Pursuit trapper that can remove hazards from the field. Its very nice defensive typing grants it an immunity to Psychic-type moves and a weakness to only Ground. However, this one weakness leaves Stunky vulnerable to Pokemon like Diglett, Mudbray, and Drilbur, which are very common. Unfortunately for Stunky, its abilities are mediocre at best; Stench doesn't really help Stunky do its job at all, and Aftermath is rarely useful. Stunky also struggles offensively because it lacks physical coverage options, and it typically has a hard time doing anything aside from Pursuit trapping and removing hazards. Stunky's complete lack of recovery leaves it prone to being worn down over the course of the battle. Alolan Grimer is almost always a better Pursuit trapper due to its better bulk and access to Knock Off.
