Absol

Absol has a fearsome Attack stat, which in conjunction with Knock Off and Choice Band makes it very hard to switch into. Its good coverage options in Superpower and Play Rough allow it to hit Steel-, Dark-, and Fighting-types like Aggron, Shiftry, Hitmonchan, and Gurdurr. It also has access to Swords Dance to further its wallbreaking potential and Sucker Punch, which makes it a very useful tool against offensive Pokemon and can often be used to sweep after a boost. However, Absol relies greatly on Sucker Punch to outspeed faster Pokemon because of its rather lacking base 75 Speed stat, which can be played around with passive moves like Substitute from Pokemon like Oricorio-G. It's also still easily revenge killed by Pokemon like Silvally-Fairy and Alolan Persian, which don't care about Sucker Punch. Due to its lackluster bulk, Absol can easily get KOed throughout the match in general. Finally, Absol sees heavy competition as a Dark-type for a team slot due to the presence of Alolan Raticate and Skuntank; the former has a lot more power behind its moves thanks to Hustle, while the latter provides a lot more utility and is a lot more easy to fit on a team.
