What it does on the ladder
Gourgeist-Large appears on 0.07% of Regulation M-B teams, which
is 206th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Protect, on 99.8% of sets.
The item is usually Focus Sash at 99.4%.
The ability is split: Frisk on 100%, Pickup on 0% and Insomnia 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
Gourgeist-Large is number 711 in the National Dex, a Kalos Pokémon, Ghost and Grass
with a base stat total of 494 — 138th of the 234 Pokémon
legal in this regulation. Its best stat is Defense at 122, 22nd
in the format; its weakest is Sp. Atk at 58, 183rd.
It can have Pickup, Frisk and Insomnia.
The Champions module tiers it UU.
It sits in a 2-stage line: Pumpkaboo-Large → Gourgeist-Large.
Not all of that line is legal in this regulation — Pumpkaboo-Large is not.
What gets through
As Ghost and Grass, 5 of the eighteen attacking types do extra damage to it. It
resists 4 and is immune to 2. The board above
has all of it. 6 other legal Pokémon share the same typing and the same board: Sinistcha, Trevenant, Gourgeist-Super, Decidueye, Gourgeist 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 Gourgeist-Large takes extra damage from.
- Kingambit — Sucker Punch (Dark, ×2), on 99.8% of its sets
- Incineroar — Flare Blitz (Fire, ×2), on 91.2% of its sets
- Charizard-Mega-Y — Heat Wave (Fire, ×2), on 99.2% of its sets
- Basculegion — Last Respects (Ghost, ×2), on 99.9% of its sets
- Pelipper — Hurricane (Flying, ×2), on 98.1% of its sets
- Staraptor-Mega — Brave Bird (Flying, ×2), on 83.4% of its sets
Against its own formes
Gourgeist has 4 legal formes in this regulation and they share a
typing, so the only thing separating them is the stat line.
It is not the extreme in any stat — it is the middle option.
The others are Gourgeist-Super, Gourgeist and Gourgeist-Small.
Speed and weight
At level 50 with a boosting nature and full investment, Gourgeist-Large reaches
133 Speed; left uninvested with a neutral nature it sits at
89. 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 14 kg, so Grass Knot and Low Kick hit it for 40 base
power. That is a real consideration in a format where both are common.
Its move pool
Gourgeist-Large learns 82 moves in the Champions data.
41 of them do damage, across 12 of the eighteen
types, and 14 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Power Whip at 120 base power, though the biggest number in the pool is Explosion at 250.
It also has priority: Shadow Sneak at +1.
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.
