What it does on the ladder
Clefable appears on 0.56% of Regulation M-B teams, which
is 96th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Follow Me, on 96.9% of sets.
The item is usually Sitrus Berry at 56.2%.
The ability is split: Unaware on 83.5%, Magic Guard on 14.6% and Cute Charm on 1.8%.
Those are Smogon's published usage figures, not anything measured here, and they describe what
the ladder plays rather than what is strongest. The full set is in the panel above.
The Pokémon itself
Clefable is number 36 in the National Dex, a Kanto Pokémon, Fairy
with a base stat total of 483 — 176th of the 234 Pokémon
legal in this regulation. Its best stat is HP at 95, 43rd
in the format; its weakest is Speed at 60, 171st.
It can have Cute Charm, Magic Guard and Unaware.
The Champions module tiers it OU.
It sits in a 3-stage line: Cleffa → Clefairy → Clefable.
Not all of that line is legal in this regulation — Cleffa and Clefairy are not.
What gets through
As Fairy, 2 of the eighteen attacking types do extra damage to it. It
resists 3 and is immune to 1. The board above
has all of it. 6 other legal Pokémon share the same typing and the same board: Sylveon, Alcremie, Aromatisse, Floette-Eternal, Florges and others.
What threatens it
Smogon publishes no head-to-head checks-and-counters data for doubles formats, so this list is
computed, not measured: the most-played Regulation M-B Pokémon carrying a damaging
move of a type Clefable takes extra damage from.
- Kingambit — Iron Head (Steel, ×2), on 67.8% of its sets
- Sneasler — Dire Claw (Poison, ×2), on 63% of its sets
- Archaludon — Flash Cannon (Steel, ×2), on 94.9% of its sets
- Gholdengo — Make It Rain (Steel, ×2), on 99.5% of its sets
- Venusaur — Sludge Bomb (Poison, ×2), on 97.2% of its sets
- Metagross-Mega — Iron Head (Steel, ×2), on 66.6% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Clefable reaches
123 Speed; left uninvested with a neutral nature it sits at
80. Invested, it outruns 1 of the 20
most-used Pokémon in the regulation when they are invested too — which is the comparison that
decides who moves first.
It weighs 40 kg, so Grass Knot and Low Kick hit it for 60 base
power. That is a real consideration in a format where both are common.
Its move pool
Clefable learns 160 moves in the Champions data.
83 of them do damage, across 16 of the eighteen
types, and 7 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Misty Explosion at 100 base power, though the biggest number in the pool is Focus Punch at 150.
It has no priority move, so it moves in Speed order every turn.
That pool is what the team builder reads from when you seat it, and the
damage calculator will take it as the attacker with
the form already chosen.
