Life Orb Clefable is undeniably amazing, and I've noticed that some people have struggled to deal with it a lot, so I'd like to dedicate this post to checking and countering Life Orb Clefable. Also, I think Clefable would be worse without Dynamax because a huge part of why I like it so much is that it can Dynamax in response to basically anything and beat it defensively, such as Gyarados for example, but that's something for another time. Now, onto some counterplay to Clefable.
I want to talk about this first because I don't think it's recognized enough by people when facing Life Orb Clefable, and while it's definitely not good counterplay to crutch on by any means, I've found that a lot of Clefable that tend to be slower than Mandibuzz. This in my experience actually enables quite a lot of counterplay, as Mandibuzz can comfortably use Knock Off against Clefable provided that they are slower. A Clefable without Life Orb, is quite weak; without it, Pokemon such as Corviknight and your own Life Orb Clefable turn into relatively solid checks to it.
Another very notable check is specially defensive Clefable. Being able to check Dragapult, Clefable, and Hydreigon in one slot is of great value for a lot of bulkier teams, giving specially defensive Clefable a solid place on those teams. Besides that, Clefable is one of the few Pokemon with access to Wish, which can give you an upperhand if your team is slowly being worn down by Life Orb Clefable.
Rotom-H is another Pokemon that I don't think is looked at enough. It's a Choice Scarf user that provides great utility and can switch into Life Orb Clefable atleast 3 times, provided that Stealth Rock are not up, and can force it out with the threat of Thunder Wave and Trick. Beyond that, I've also seen some people run RestTalk Rotom-H, which can consistently switch into Life Orb Clefable throughout games, and is often able to make progress thanks to Volt Switch.
Over the past week or so, I've also seen people try to adapt to Life Orb Clefable with specially defensive Gastrodon and Hippowdon. They're generally solid checks, but if Clefable were to Dynamax, they can be overwhelmed pretty well in my experience. Besides checking Life Orb Clefable, Gastrodon and Hippowdon can also provide you with some other utility. Gastrodon's the most consistent check to Dracovish, and being able to wall out Rotom-H and Rotom-W is of great value right now. Hippowdon can also provide teams with a Stealth Rock setter and it's a pretty decent check to Dracozolt as well.
The Pokemon that I've mentioned so far are defensively-oriented ways of checking Life Orb Clefable. I'd also like to point out some Pokemon that are good, more offensively-oriented checks to Clefable, although you have to keep in mind that Clefable can beat most of them through Dynamaxing in a one-on-one.
Although it can't switch into Clefable consistently because of the threat of Flamethrower, Excadrill is able to take every other move very well and it can often be devastating to deal with if it gets in safely against Pokemon like Clefable.
Although they're quickly worn down by Clefable, Gengar, Toxtricity, and Cinderace can switch into Clefable atleast once or twice in a match, and similarly to Excadrill, they can be super hard to deal with if they're granted the opportunity. I'd also like to shoutout the person that's running Assault Vest Toxtricity purely to check Clefable and opposing Toxtricity.
I hope this post serves as a good way for people to look into checking Life Orb Clefable. Of course, if you have anything to add onto my post that you think I missed, I, and I'm sure most other people too, would love to hear about it!
