Crawdaunt

Crawdaunt is a true powerhouse and a terrifying wallbreaker thanks to Adaptability and its sky-high Attack stat. It has very powerful STAB moves in the form of Knock Off and Crabhammer, which are very hard to switch into. Additionally, Swords Dance and Aqua Jet give Crawdaunt a great cleaning tool and can somewhat fix up its poor Speed. Crawdaunt also has an excellent matchup against slower defensive teams, as they struggle to take boosted hits. However, Crawdaunt does have numerous flaws; it has low Speed, which is only slightly remedied by Aqua Jet, and is extremely frail, struggling to take even resisted hits, making it very hard to set up or switch in safely.
