MurkrowDrill Peck / Night Shade / Astonish / Embargo
GolbatPoison Fang / Air Cutter / Bite / Supersonic
Sneaselholds Sitrus Berry • Slash / Ice Punch / Quick Attack / Screech
Danger notes
Cyrus's Sneasel is the strongest immediate threat, backed by fast Murkrow and Golbat.
Practical counters
Rock and Electric cover both fliers; Fighting or Fire handles Sneasel. Avoid slow setup because his team is built around speed.
Commander SaturnCommander Saturn • source ID 409Full team
KadabraPsychic / Shock Wave / Recover / Embargo
BronzorGyro Ball / Extrasensory / Shadow Ball / Confuse Ray
Toxicroakholds Sitrus Berry • Poison Jab / Brick Break / X Scissor / Swagger
Danger notes
The rematch uses the same Kadabra/Bronzor/Toxicroak structure at higher levels.
Practical counters
Prioritize fast pressure on Kadabra, identify Bronzor's ability, and reserve Psychic or Ground damage for Toxicroak.
Commander MarsCommander Mars • source ID 528Full team
BronzorGyro Ball / Extrasensory / Light Screen / Confuse Ray
GolbatAir Cutter / Bite / Poison Fang / Confuse Ray
Puruglyholds Sitrus Berry • Slash / Shadow Claw / Aerial Ace / Hypnosis
Danger notes
Mars uses a fast Golbat line and a physically powerful Purugly.
Practical counters
Electric/Rock coverage and a Fighting answer give the cleanest split.
Commander JupiterCommander Jupiter • source ID 407Full team
BronzorGyro Ball / Extrasensory / Rock Slide / Reflect
GolbatSludge Bomb / Air Cutter / Giga Drain / Mean Look
Skuntankholds Sitrus Berry • Night Slash / Poison Jab / Flamethrower / Smokescreen
Danger notes
Skuntank remains Jupiter's closer while Bronzor and Golbat drain resources first.
Practical counters
Save Ground for Skuntank, Electric or Rock for Golbat, and attack Bronzor through the weakness its ability leaves active.
Galactic Boss CyrusGalactic Boss • source ID 404Full team
HonchkrowDrill Peck / Dark Pulse / Steel Wing / Embargo
CrobatCross Poison / Air Slash / Bite / Confuse Ray
GyaradosGiga Impact / Aqua Tail / Ice Fang / Earthquake
Weavileholds Sitrus Berry • Night Slash / Ice Punch / Brick Break / X Scissor
Danger notes
Weavile and Gyarados create opposite defensive demands, while Crobat is extremely fast and Honchkrow hits hard.
Practical counters
Bring Fighting for Weavile, Electric for Gyarados/Crobat, and Rock or Ice coverage for the fliers. Preserve answers across the full four-Pokémon fight.

Luxrayholds Sitrus Berry • Charge Beam / Thunder Fang / Crunch / Thunder Wave
Danger notes
Volkner's Ambipom and Octillery punish a one-note Ground plan, while Luxray closes with high power.
Practical counters
Ground is central but not sufficient alone. Grass or Electric handles Octillery; Fighting checks Ambipom; preserve the Ground user for Raichu and Luxray.
