What it does on the ladder
Azumarill appears on 0.35% of Regulation M-B teams, which
is 115th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Play Rough, on 97.6% of sets.
The item is usually Sitrus Berry at 79.8%.
The ability is split: Huge Power on 96.1%, Sap Sipper on 3.5% and Thick Fat on 0.4%.
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
Azumarill is number 184 in the National Dex, a Johto Pokémon, Water and Fairy
with a base stat total of 420 — 224th of the 234 Pokémon
legal in this regulation. Its best stat is HP at 100, 31st
in the format; its weakest is Speed at 50, 193rd.
It can have Thick Fat, Huge Power and Sap Sipper.
The Champions module tiers it UU.
It sits in a 3-stage line: Azurill → Marill → Azumarill.
Not all of that line is legal in this regulation — Azurill and Marill are not.
What gets through
As Water and Fairy, 3 of the eighteen attacking types do extra damage to it. It
resists 6 and is immune to 1. The board above
has all of it. One other legal Pokémon shares the same typing and the same board: Primarina.
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 Azumarill takes extra damage from.
- Charizard-Mega-Y — Solar Beam (Grass, ×2), on 82.2% of its sets
- Sinistcha — Matcha Gotcha (Grass, ×2), on 97.9% of its sets
- Sneasler — Dire Claw (Poison, ×2), on 63% of its sets
- Farigiraf — Thunderbolt (Electric, ×2), on 59.2% of its sets
- Archaludon — Electro Shot (Electric, ×2), on 98.6% of its sets
- Venusaur — Sludge Bomb (Poison, ×2), on 97.2% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Azumarill reaches
112 Speed; left uninvested with a neutral nature it sits at
70. 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 28.5 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
Azumarill learns 106 moves in the Champions data.
65 of them do damage, across 12 of the eighteen
types, and 20 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Hydro Pump at 110 base power, though the biggest number in the pool is Focus Punch at 150.
It also has priority: Aqua Jet 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.
