What it does on the ladder
Aegislash appears on 0.82% of Regulation M-B teams, which
is 76th of the 282 Pokémon with enough games to measure.
The move it almost always carries is King's Shield, on 80.9% of sets.
The item is usually Spell Tag at 30%.
Every one of them runs Stance Change.
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
Aegislash is number 681 in the National Dex, a Kalos Pokémon, Steel and Ghost
with a base stat total of 500 — 114th of the 234 Pokémon
legal in this regulation. Its best stat is Defense at 140, 11th
in the format; its weakest is Sp. Atk at 50, 210th.
Its only ability is Stance Change.
The Champions module tiers it OU.
It sits in a 3-stage line: Honedge → Doublade → Aegislash.
Not all of that line is legal in this regulation — Honedge and Doublade are not.
What gets through
As Steel and Ghost, 4 of the eighteen attacking types do extra damage to it. It
resists 9 and is immune to 3. The board above
has all of it. One other legal Pokémon shares the same typing and the same board: Gholdengo.
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 Aegislash 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
- Garchomp — Earthquake (Ground, ×2), on 85.7% 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
- Gholdengo — Shadow Ball (Ghost, ×2), on 99.1% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Aegislash reaches
123 Speed; left uninvested with a neutral nature it sits at
80. 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 53 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
Aegislash learns 67 moves in the Champions data.
36 of them do damage, across 11 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 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.
