What it does on the ladder
Roserade appears on 0.04% of Regulation M-B teams, which
is 241st of the 282 Pokémon with enough games to measure.
The move it almost always carries is Sludge Bomb, on 73.7% of sets.
The item is usually Focus Sash at 36.8%.
The ability is split: Natural Cure on 57.9%, Technician on 33.1% and Poison Point on 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
Roserade is number 407 in the National Dex, a Sinnoh Pokémon, Grass and Poison
with a base stat total of 515 — 87th of the 234 Pokémon
legal in this regulation. Its best stat is Sp. Atk at 125, 20th
in the format; its weakest is HP at 60, 207th.
It can have Natural Cure, Poison Point and Technician.
The Champions module tiers it UU.
It sits in a 3-stage line: Budew → Roselia → Roserade.
Not all of that line is legal in this regulation — Budew and Roselia are not.
What gets through
As Grass and Poison, 4 of the eighteen attacking types do extra damage to it. It
resists 5. The board above
has all of it. 3 other legal Pokémon share the same typing and the same board: Venusaur, Vileplume, Victreebel.
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 Roserade takes extra damage from.
- Incineroar — Flare Blitz (Fire, ×2), on 91.2% of its sets
- Charizard-Mega-Y — Heat Wave (Fire, ×2), on 99.2% of its sets
- Farigiraf — Psychic (Psychic, ×2), on 54.4% 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
- Aerodactyl-Mega — Dual Wingbeat (Flying, ×2), on 91.2% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Roserade reaches
156 Speed; left uninvested with a neutral nature it sits at
110. Invested, it outruns 12 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 14.5 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
Roserade learns 75 moves in the Champions data.
37 of them do damage, across 8 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 has no priority move, so it moves in Speed order every turn.
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.
