Pokémon Champions Ranked Season M-4 Has Ended
Pokémon Champions Ranked Battles Season M-4 ended on August 5, 2026. The completed ladder used Regulation Set M-B across Single and Double Battles.
Game summary
News summary
Season M-4 used Regulation Set M-B for both Single Battle and Double Battle competition.
Champion Tier and Master Ball Tier Ranks 1–3 had been open since July 15, one week after the season began.
Eligible players can collect rewards based on their final rank or their placement inside the Master Ball Tier.
A Trainer needed to complete at least one match with a win or loss during M-4 to qualify for the season rewards.
Event overview
The M-4 ladder is now closed, so wins and losses no longer change its final standings or Master Ball rating placements.
Reward eligibility is tied to participation rather than a minimum rank: one completed Single or Double Battle is sufficient for the game to register a season result.
Players can open Ranked Battles, select Check Rules and view the Rewards section to see the items attached to their final M-4 result.
Key details
The completed season ran for 28 days under Pokémon Champions’ M-B ruleset.
