Clefable A+ to S
it’s the perfect utility mon in a sense that it can always get up sr and beat all spinners/defoggers. it’s ability + typing make it an excellent pivot or sweeper as well as a valid move pool to boot. if it wasn’t for its “poor stats” i think it’d be too much to handle. it has great utility in sr, twave, knock off, healbell, encore etc. the unaware version stops set up sweepers and clefable is just a mon that can be slapped on to any type of team. it has solid recovery in soft boiled/heal bell and two amazing abilities. It can check a whole bunch of threats in the metagame just in itself so yeah, clefable to S for me.
OK just saying it doesn't beat Excadrill as a spinner and Natural Cure Starmie is a pretty damn good spinner on it as T-Wave obviously doesn't mean too much, if it is a rare T-Bolt Clef then Reflect Type is a pretty easy move. That's just a slight nitpick.
Anyway to my thoughts on it:
It doesn't have a stat over 95. This is a terrible hindrance to it, and it is pressured massively by most offensive or balance teams to be taking hits. I'll use the Magic Guard Calm Mind set and the Physically Defensive set:
252 SpA Life Orb Thundurus Thunderbolt vs. 252 HP / 96+ SpD Clefable: 165-196 (41.8 - 49.7%) -- guaranteed 3HKO after Leftovers recovery
252 SpA Life Orb Thundurus Thunderbolt vs. 252 HP / 4 SpD Clefable: 203-239 (51.5 - 60.6%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
252 SpA Life Orb Latios Psyshock vs. 252 HP / 160 Def Clefable: 181-214 (45.9 - 54.3%) -- 5.5% chance to 2HKO after Leftovers recovery
252 SpA Life Orb Latios Psyshock vs. 252 HP / 252+ Def Clefable: 149-177 (37.8 - 44.9%) -- guaranteed 3HKO after Stealth Rock and Leftovers recovery
252 Atk Mega Lopunny Return vs. 252 HP / 160 Def Clefable: 184-217 (46.7 - 55%) -- 14.1% chance to 2HKO after Leftovers recovery
252 Atk Mega Lopunny Return vs. 252 HP / 252+ Def Clefable: 153-180 (38.8 - 45.6%) -- guaranteed 3HKO after Stealth Rock and Leftovers recovery
Ok that's just a small example of offensive sweepers or just generally not wall breaker Pokemon. Clef needs to choose between SpDef or Defensive to be able to actually take hits from specific things. With ~10% prior damage, it basically loses to all these Pokemon, meaning that in any given game if it wants to be able to take strong hits, it needs to maintain full health and no status if Unaware or even Para if Magic Guard. Now if we look at actual wallbreakers or things with naturally hard hits:
232 SpA Pixilate Mega Gardevoir Hyper Voice vs. 252 HP / 96+ SpD Clefable: 202-238 (51.2 - 60.4%) -- 91.4% chance to 2HKO after Leftovers recovery
232 SpA Pixilate Mega Gardevoir Hyper Voice vs. 252 HP / 4 SpD Clefable: 246-291 (62.4 - 73.8%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
252 Atk Aerilate Mega Pinsir Return vs. 252 HP / 160 Def Clefable: 262-310 (66.4 - 78.6%) -- guaranteed 2HKO after Leftovers recovery
252 Atk Aerilate Mega Pinsir Return vs. 252 HP / 252+ Def Clefable: 217-256 (55 - 64.9%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
252+ Atk Life Orb Adaptability Crawdaunt Crabhammer vs. 252 HP / 160 Def Clefable: 312-369 (79.1 - 93.6%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Life Orb Adaptability Crawdaunt Crabhammer vs. 252 HP / 252+ Def Clefable: 260-307 (65.9 - 77.9%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
252+ Atk Life Orb Huge Power Diggersby Return vs. 252 HP / 160 Def Clefable: 298-352 (75.6 - 89.3%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Life Orb Huge Power Diggersby Return vs. 252 HP / 252+ Def Clefable: 246-290 (62.4 - 73.6%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
It can't switch in on any strong attacks, it's not even close. It's simply not bulky enough due to its poor base stats that to get a free switch you have to sac.
I'm not arguing that it's bad per se, but as a defensive Pokemon what makes it
that much better than Mega Sableye, or Gliscor, both with much better stats across the board (give or take, see: Mega Sableye's speed stat).
Look at all the S-Ranked Pokemon:
Keldeo's ability to break through its hard checks with Scald makes it amazing, as a Revenge killer, late game cleaner, wallbreaker, and so on.
Mega Metagross is lucky it's not Ubers as far as I'm concerned. It's so good in OU with the ability to hit like a wallbreaker but still with 110 Base Speed and better bulk in every stat than Skarmory, plus coverage for essentially everything.
Landorus is of course probably the best thing in OU atm. It's just amazing as STAB Earth Power hits so freaking hard while it's got coverage for almost everything. It can support the team with Stealth Rocks and pull of Rock Polish as well as 4 attacks sets ridicuously easily.
Mega Altaria has so many sets, supports the team at the same time as being offensive with Heal Bell, sets up on many many things, can break through checks and requires little team support at all.
Compared to:
Clefable has set counters that it can't break through like Keldeo. It can hinder them (T-Wave Heatran, M-Venusaur, Talonflame (also thunderbolt), but that depends on its moveset, and Chansey is basically a 100% wall regardless of anything and just stalls out Clef's recovery.
MMeta's best asset is ridiculously good stats all around. Pretty much the opposite of Clef. Although I'll admit the coverage options is similar, but something like SubCM Raikou just sets up on pretty much every set.
Landorus is in a great spot in the current meta in that it's not forced to run Psychic for Venusaur (among many other factors) so it can get really good coverage. Clef hasn't really had anything happen to the meta that made it stand out- if anything, we're now seeing MMeta everywhere, Lando with Sludge Wave, Bisharp and Scizor running amuck. The fact that people need Mega Altaria checks and most of the checks for Altaria overlap with checks for Clef means it's not in the best spot.
Mega Altaria is actually similar to Clefable in that it can be an offensive, defensive and support mon at the same time. However, Altaria has many more sets and hits a shitload harder, while being able to use the fact that it walls something by actually setting up while Clef often just falls into a PP stallfest. Clef is better as a support mon without a doubt, but I'm arguing that just this doesn't give it the edge.
OK, so it's not directly comparable to most of these, although I tried to look for aspects that would make them comparable. But, I have to say that all up, it's really not standing out in this meta and that the current S-ranks are better than it by far, imo.
Clefable stay A+
