Optimal Gym Attack Team in Pokémon GO — Shortest-Path Analysis (2026 Update)

“What’s the best 6-Pokémon team for taking down a gym?” The answer depends on which gym you’re attacking, but if you optimize for the average gym defender pool — which is dominated by Blissey, Chansey, Togekiss, Dragonite, Metagross, and Wobbuffet — there’s a mathematically optimal answer. This guide presents the optimal gym attack team derived from a shortest-path optimization over the most common defender lineups.

The Optimization Setup

This analysis treats gym attack as a shortest-path problem: minimize total clear time across the 6 defenders. The assumptions:

  • Defender lineup: The most common gym defender mix — Blissey + Chansey (Normal), Togekiss (Flying), Dragonite (Dragon/Flying), Metagross (Steel/Psychic), Wobbuffet (Psychic) — fixed in attack order.
  • Attacker pool: One Pokémon from each of the 18 types, picked greedily for fastest clear vs. its assigned defender slot.
  • Switching: Attackers can be switched freely; we compute the path that minimizes total time-to-faint (TTF) across all defenders.
  • Build assumption: All attackers at PL40 with optimal Fast + Charged moves, neutral weather.

The Optimal 5 Picks

Each Pokémon below was selected because it minimizes TTF against its specific defender role.

1

Lucario

Lucario — Required Type #1 (Fighting)

FightingSteel The Blissey / Chansey wall is the longest TTF in any gym, and Fighting is the only type that breaks it efficiently. Lucario’s Counter + Aura Sphere is the best Fighting moveset short of Mega Lucario.

  • Defender target: Blissey / Chansey
  • Why Lucario: Top non-Mega Fighting DPS
2

Pheromosa

Pheromosa — Required Type #2 (Bug)

BugFighting Wobbuffet (Psychic) needs Bug coverage; Pheromosa wins the TTF on raw Attack stat. Gengar or Darkrai are within 1 second and work as substitutes.

  • Defender target: Wobbuffet / Psychic-types
  • Substitutes: Gengar, Darkrai (Ghost/Dark)
3

Xurkitree

Xurkitree — Required Type #2 (Electric)

Electric Togekiss (Flying) needs Electric coverage. Xurkitree’s Thunder Shock + Discharge is the fastest non-Mega clear.

  • Defender target: Togekiss / Flying-types
  • Substitutes: Regieleki
4

Mamoswine

Mamoswine — Required Type #2 (Ice)

IceGround Dragonite (Dragon/Flying) is double-weak to Ice. Mamoswine’s Powder Snow + Avalanche is the most efficient non-Mega Ice option, and Ground secondary covers Steel-Electric matchups.

  • Defender target: Dragonite / Dragon-types
  • Substitutes: Glaceon (Ice DPS leader)
5

Reshiram

Reshiram — Free Slot (Fire)

FireDragon Metagross (Steel/Psychic) is weak to Fire. Reshiram’s Fire Fang + Fusion Flare clears Metagross cleanly. The 6th slot is fully flexible — pick anything you enjoy.

The Type Logic Behind the Picks

The optimization reduces to two type categories plus a free slot:

Required Type 1 — Fighting (counters Normal)

Blissey and Chansey are the longest-TTF gym defenders. Without Fighting, the entire team’s clear time blows up. Lucario is the cleanest non-Mega Fighting attacker, but Mega Mewtwo X (Fighting) and Conkeldurr / Machamp (Fighting) work as substitutes.

Required Type 2 — Anti-Fighting-resist coverage

Pokémon that resist Fighting (Psychic / Flying / Fairy) need to be hit by their respective weakness types: Bug / Ghost / Dark / Electric / Ice / Rock / Steel. The default optimal picks are Bug (Pheromosa for Wobbuffet), Electric (Xurkitree for Togekiss), and Ice (Mamoswine for Dragonite). One of each fills three of the four open slots.

Free slot — Steel coverage filler

The remaining slot deals with Metagross-class defenders that resist both Required Type 1 and Required Type 2. Fire (Reshiram, Chandelure) is the natural fit. Alternative: pick a “fun” attacker for win-streak farming — the math doesn’t care.
