Official Regulation M-B Doubles Overview Goes Live

Pokemon.com has posted an official overview for Pokemon Champions Regulation M-B Double Battles, giving competitive players a reference point for the current doubles ruleset.

For PokemonHelper readers, the practical takeaway is simple: if you are building or revising teams for M-B, this is the rules page to check before locking in spreads, Mega choices, and practice partners. Regulation documents are especially important in Champions because the game’s format is not a direct copy of Scarlet and Violet VGC. Team legality, available mechanics, and battle assumptions can differ, so relying on older habits can create avoidable prep mistakes.

Until players fully solve the M-B field, expect early ladder and tournament testing to focus on identifying which cores remain consistent under the listed restrictions. Doubles formats usually settle around speed control, positioning, defensive pivots, and high-impact Mega turns, so even a small legality difference can change which archetypes are worth preparing for.

If you are entering M-B events, review the official overview first, then test with those limits in mind rather than retrofitting a previous-format team.
