Persian

Although Persian is faster than most of the unboosted metagame and has access to Nasty Plot and Technician, it is unfortunately a terrible Pokemon. None of its stats are particularly good outside of its Speed, which means it won't hit very hard, can't easily set up, and is easy to revenge kill with priority moves and Choice Scarf users. Persian is outclassed as a specially offensive Normal-type by Drampa, which hits much harder without even needing to set up and also has a secondary Dragon typing. Persian is also outclassed as a Nasty Plot sweeper by Alolan Raichu and Alolan Persian, with the former having a higher Special Attack stat and using its secondary Psychic typing to threaten Pokemon like Hitmonchan and Roselia, while the latter's access to Fur Coat provides it with actual defensive presence and makes setting up much easier.
