What it does on the ladder
Musharna appears on 0.06% of Regulation M-B teams, which
is 217th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Trick Room, on 85.7% of sets.
The item is usually Colbur Berry at 34.1%.
The ability is split: Telepathy on 83.2%, Forewarn on 11.9% and Synchronize on 5%.
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
Musharna is number 518 in the National Dex, a Unova Pokémon, Psychic
with a base stat total of 487 — 163rd of the 234 Pokémon
legal in this regulation. Its best stat is HP at 116, 7th
in the format; its weakest is Speed at 29, 232nd.
It can have Forewarn, Synchronize and Telepathy.
The Champions module tiers it UU.
It sits in a 2-stage line: Munna → Musharna.
Not all of that line is legal in this regulation — Munna is not.
What gets through
As Psychic, 3 of the eighteen attacking types do extra damage to it. It
resists 2. The board above
has all of it. 6 other legal Pokémon share the same typing and the same board: Meowstic, Espathra, Reuniclus, Espeon, Alakazam 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 Musharna takes extra damage from.
- Kingambit — Sucker Punch (Dark, ×2), on 99.8% of its sets
- Incineroar — Throat Chop (Dark, ×2), on 44.4% of its sets
- Basculegion — Last Respects (Ghost, ×2), on 99.9% of its sets
- Gholdengo — Shadow Ball (Ghost, ×2), on 99.1% of its sets
- Blastoise-Mega — Dark Pulse (Dark, ×2), on 93.2% of its sets
- Mawile-Mega — Sucker Punch (Dark, ×2), on 91.6% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Musharna reaches
89 Speed; left uninvested with a neutral nature it sits at
49. Invested, it outruns 0 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 60.5 kg, so Grass Knot and Low Kick hit it for 80 base
power. That is a real consideration in a format where both are common.
Its move pool
Musharna learns 74 moves in the Champions data.
26 of them do damage, across 8 of the eighteen
types, and 8 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Future Sight at 120 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.
