What it does on the ladder
Trevenant appears on 0.05% of Regulation M-B teams, which
is 226th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Trick Room, on 73.2% of sets.
The item is usually Sitrus Berry at 92.3%.
The ability is split: Harvest on 91.8%, Frisk on 6.3% and Natural Cure on 1.9%.
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
Trevenant is number 709 in the National Dex, a Kalos Pokémon, Ghost and Grass
with a base stat total of 474 — 194th of the 234 Pokémon
legal in this regulation. Its best stat is Attack at 110, 63rd
in the format; its weakest is Speed at 56, 184th.
It can have Natural Cure, Frisk and Harvest.
The Champions module tiers it UU.
It sits in a 2-stage line: Phantump → Trevenant.
Not all of that line is legal in this regulation — Phantump 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, Gourgeist-Large, 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 Trevenant 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
Speed and weight
At level 50 with a boosting nature and full investment, Trevenant reaches
118 Speed; left uninvested with a neutral nature it sits at
76. 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 71 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
Trevenant learns 100 moves in the Champions data.
53 of them do damage, across 11 of the eighteen
types, and 18 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Leaf Storm at 130 base power, though the biggest number in the pool is Giga Impact at 150.
It also has priority: Sucker Punch 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.
