What it does on the ladder
Espeon appears on 0.10% of Regulation M-B teams, which
is 193rd of the 282 Pokémon with enough games to measure.
The move it almost always carries is Power Gem, on 71.5% of sets.
The item is usually Focus Sash at 69.9%.
The ability is split: Magic Bounce on 99.2% and Synchronize on 0.8%.
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
Espeon is number 196 in the National Dex, a Johto Pokémon, Psychic
with a base stat total of 525 — 66th of the 234 Pokémon
legal in this regulation. Its best stat is Sp. Atk at 130, 11th
in the format; its weakest is Defense at 60, 214th.
It can have Synchronize and Magic Bounce.
The Champions module tiers it UU.
It sits in a 2-stage line: Eevee → Espeon.
Not all of that line is legal in this regulation — Eevee 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, Alakazam, Musharna 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 Espeon 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, Espeon reaches
178 Speed; left uninvested with a neutral nature it sits at
130. Invested, it outruns 15 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 26.5 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
Espeon learns 107 moves in the Champions data.
47 of them do damage, across 11 of the eighteen
types, and 11 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 also has priority: Quick Attack 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.
