Editor's verdict

This week, focus on building Primal Groudon and Mega Mewtwo Y. Primal Groudon dominates with its immense bulk and powerful Fire and Ground moves, while Mega Mewtwo Y offers unmatched damage output and versatility with its Psychic-type moves. Both are essential for tackling the current meta and can turn the tide in battles.

Methodology

Stat product: Perfect 15/15/15 at level 50 — no cap, so raw stats win.
Moveset: Every fast + charged pair is simulated with the real PvP damage formula; energy generation is weighted for shield pressure.
Coverage: Move effectiveness is averaged across all 18 defending types.
Bulk: Defensive typing adjusts effective HP against the average attacker.
Shadow: +20% Attack, −17% Defense, flowed through both sides.

Final score

Score = Offense × Survivability^0.5

Tier cut-offs

Tier S: Top 5% or top 5
Tier A: Top 15% or top 12
Tier B: Top 25% or top 25
Tier C: Top 35% or top 38
Tier D: Everything else

What we do not simulate: round-robin matchups, second charged moves, shield baiting and lead/closer roles. The ranking measures how a Pokemon performs against the average meta, not against one specific opponent — so treat it as a shortlist, not a verdict on any single matchup.

Editor's notes

The state of Master League and how to build around it.

Master League meta — the state of play

The Master League meta is currently heavily influenced by Mega Evolutions and Primal Pokémon. With the introduction of powerful options like Primal Groudon and Mega Mewtwo variants, the landscape is shifting toward high-damage output and tanky Pokémon. Expect a lot of pressure from these top-tier picks, making it crucial to adapt your team accordingly.

Core picks & archetypes

Primal Groudon, Mega Mewtwo X, and Mega Mewtwo Y are the cornerstone choices defining the ladder. Shadow Pokémon, particularly Shadow Dialga and Shadow Reshiram, are also making waves due to their enhanced damage potential. Mega Gallade and Mega Metagross are strong contenders as well, providing unique coverage against popular threats.

Team building — leads, safe swaps & closers

For an effective team this week, consider Primal Groudon as your lead due to its bulk and ability to threaten a wide range of opponents. As a safe swap, Mega Mewtwo Y can absorb damage while dishing out high DPS. For a closer, Shadow Dialga excels, especially against Psychic- and Flying-types that may come in after your lead. This combination allows for a balanced approach to offensive and defensive strategies.

IVs & investment

In the Master League, maximizing CP is crucial since there's no cap. Focus on IVs that enhance attack and bulk. Aim for a 15/15/15 spread for your top picks like Primal Groudon and Mega Mewtwo Y. Investing in these Pokémon will ensure they perform at their peak, especially when facing other high-tier threats.

Threats to watch

Be wary of Mega Garchomp and Mega Salamence, as their Dragon- and Ground-type moves can threaten your top picks. Utilize Fairy-types or Ice-type moves to combat them effectively. Additionally, watch out for Shadow Reshiram, which can dish out serious damage if not countered quickly. A solid Dragon-type or Fairy-type Pokémon can help mitigate their impact on your team.
