Slowking

Slowking has a niche as one of the only effective Assault Vest users in the tier, and coupled with its very good HP and Special Defense stats, it can act as an effective blanket check to special attackers. Some of the Pokemon it checks include Nidoqueen, Salazzle, Gardevoir, Noivern, Swellow, and Necrozma. It has a premier ability in Regenerator that allows it to check these Pokemon throughout the match. Its extensive movepool includes a plethora of coverage and utility options like Fire Blast, Ice Beam, and Dragon Tail. However, despite all its positives, it faces stiff competition for a slot on most teams from its Psychic-type counterparts such as Slowbro and Cresselia, which possess unique advantages including better natural physical bulk. It also has a crippling weakness to Pursuit and the ever-present Knock Off. Finally, Slowking struggles to take on the plethora of strong physical attackers in the tier, even ones without super effective coverage like Donphan, Zygarde-10%, and Bewear.
