What it does on the ladder
Klefki appears on 0.19% of Regulation M-B teams, which
is 144th of the 277 Pokémon with enough games to measure.
The move it almost always carries is Light Screen, on 67.1% of sets.
The item is usually Light Clay at 52%.
The ability is split: Prankster on 100% and Magician on 0%.
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
Klefki is number 707 in the National Dex, a Kalos Pokémon, Steel and Fairy
with a base stat total of 470 — 201st of the 234 Pokémon
legal in this regulation. Its best stat is Defense at 91, 75th
in the format; its weakest is HP at 57, 217th.
It can have Prankster and Magician.
The Champions module tiers it UU.
It has no evolutions on either side; what you see is the whole line.
What gets through
As Steel and Fairy, 2 of the eighteen attacking types do extra damage to it. It
resists 9 and is immune to 2. The board above
has all of it. 2 other legal Pokémon share the same typing and the same board: Tinkaton, Mawile.
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 Klefki takes extra damage from.
- Incineroar — Flare Blitz (Fire, ×2), on 91.1% of its sets
- Garchomp — Earthquake (Ground, ×2), on 85.1% of its sets
- Charizard-Mega-Y — Heat Wave (Fire, ×2), on 99.9% of its sets
- Delphox-Mega — Heat Wave (Fire, ×2), on 99.6% of its sets
- Venusaur — Earth Power (Ground, ×2), on 71.1% of its sets
- Swampert-Mega — Earthquake (Ground, ×2), on 83.7% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Klefki reaches
139 Speed; left uninvested with a neutral nature it sits at
95. Invested, it outruns 6 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 3 kg, so Grass Knot and Low Kick hit it for 20 base
power. That is a real consideration in a format where both are common.
Its move pool
Klefki learns 66 moves in the Champions data.
28 of them do damage, across 7 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 Steel Beam at 140 base power, though the biggest number in the pool is Giga Impact 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.
