BASCULEGION
VGC GUIDE

WaterGhostUsage #2 #902

Basculegion (#902) is the #2 most-used Pokémon in Regulation M-B, built on three pillars: Water/Ghost dual typing, devastating Last Respects late-game scaling, and Swift Swim speed control in rain. This guide covers all competitive builds, SP spreads, team composition, and damage calculations.

Role Overview

Standard Build — Adaptability Sweep

With Adaptability and Choice Scarf, Basculegion enters late-game and sweeps with Last Respects. Every fainted ally adds +50 BP, and Adaptability's 2× STAB multiplier makes it virtually unwallable at 2–3 KOs. 93.2% of players run this ability.

Rain Build — Swift Swim Speed Core

Under rain, Swift Swim doubles Speed from 78 to 156, outspeeding the entire unboosted field. Rain also provides a ×1.5 boost to Water moves, making Wave Crash absurdly powerful. Pair with Pelipper or Mega Swampert as the rain setter.

Water/Ghost Typing Key Advantages
  • Fake Out immunity — Ghost-type immunity to Normal moves completely blocks Fake Out, disrupting opponent openings.
  • Near-unresisted coverage — Water + Ghost dual STAB covers nearly the entire format; Aqua Jet priority fills speed gaps.
  • 120 HP bulk — Enables tanking key hits and surviving to mid-game before unleashing scaled Last Respects.

Team Composition

Standard Offensive Core (Adaptability Build)
Garchomp48.9%

Ground/Dragon coverage; Earthquake punishes Electric checks that threaten Basculegion.

Whimsicott46.5%

Prankster Tailwind gives Basculegion priority; Encore locks disruption before sweeping.

Kingambit36.7%

Physical endgame cleaner forming a dual sweep core; counters Ghost and Grass checks.

Mega Charizard Y31.2%

Harsh Sun removes rain weather wars; special coverage completes the offensive profile.

Rain Team Core (Swift Swim Build)
PelipperRain setter

Drizzle sets rain instantly on switch-in; Damp Rock extends weather to 8 turns. Hurricane for spread damage.

Mega SwampertSwift Swim dual core

Swift Swim partner doubling Speed alongside Basculegion; Wave Crash + Earthquake dual sweep.

ArchaludonElectro Shot coverage

Fires Electro Shot in one turn under rain; provides Electric coverage against Basculegion checks.

SinistchaUtility support

Matcha Gotcha recovery and chip damage; Misty Terrain blocks status; tactical flexibility for rain.

In bring-6-pick-4 doubles, rain teams typically lead Pelipper + Mega Swampert to guarantee rain on turn 1, with Basculegion as a back-seat sweeper entering when the field is favorable. Standard teams lead Whimsicott for Prankster Tailwind, then sweep with Basculegion and Garchomp under speed support.

Counters & Checks

Hard Counters (×2 Type Weakness)
Electric
Mega Manectric / Zapdos
Electric STAB for 2× damage; outspeeds Basculegion outside rain. Highly reliable check.
Grass
Mega Venusaur / Ludicolo
Grass STAB hits 2×; Mega Venusaur's Thick Fat also walls Water attacks — double counter.
Dark
Kingambit (Sucker Punch)
Priority Sucker Punch hits Dark 2× weakness and almost always moves first.
Functional Checks
Ghost
Sinistcha / Gengar
Ghost-type attacks hit 2×; some carry Will-O-Wisp to halve physical output of the male form.
Water
Water Absorb Pokémon
Fully nullifies Wave Crash and Aqua Jet, restoring HP instead of taking damage.
Priority
Fast Priority Moves
Bullet Punch, Shadow Sneak bypass Swift Swim speed entirely, striking before rain activates.
Weather
Harsh Sunshine / Sandstorm
Weather war removes rain, cutting Swift Swim speed to 78 and removing Water's ×1.5 boost.

The most important anti-Basculegion strategy is eliminating it before Last Respects scales out of control, or weather-warring with Harsh Sunshine/Sandstorm to strip Swift Swim. Keeping an Electric or Grass check on the field forces opponents to run Flip Turn for safe pivoting, costing them offensive tempo.

Frequently Asked Questions

What is the best moveset for Basculegion in Pokémon Champions Reg M-B?+
The top set is Last Respects + Aqua Jet + Wave Crash + Protect with Adamant nature, Adaptability ability, and Choice Scarf (SP: 28 Atk / 18 Def / 20 SpD). For rain teams, swap to Swift Swim and replace Protect with Flip Turn (SP: 32 Atk / 32 Spe / 2 HP).
Is male or female Basculegion better for competitive play?+
Male Basculegion (112 Atk vs female's 92) dominates competitive play for physical Last Respects and Wave Crash sets. Female Basculegion (100 SpA vs male's 80) suits special builds with Surf, Shadow Ball, and Ice Beam as a tech pick. The meta overwhelmingly favors the male form.
What are Basculegion's weaknesses in Pokémon Champions?+
As a Water/Ghost type, Basculegion is 2× weak to Electric, Grass, Ghost, and Dark moves, and fully immune to Normal and Fighting (blocks Fake Out). Most reliable checks: fast Electric attackers like Mega Manectric, Grass types like Mega Venusaur, and Kingambit's priority Sucker Punch.
How does Swift Swim Basculegion work on rain teams?+
Swift Swim doubles Basculegion's Speed from 78 to 156 under rain, outspeeding the entire unboosted metagame. Set rain with Pelipper (Drizzle) or Mega Swampert, then sweep with rain-boosted Wave Crash (×1.5 Water power in rain). Recommended SP: 32 Atk / 32 Spe / 2 HP with Adamant nature.
