Regulation Set M-C Brings New Mega Options to Champions

Pokemon Champions is expanding its Mega Evolution ruleset with Regulation Set M-C, which will add support for Z Mega Evolutions. For competitive players, the important part is that this is a format-level change, not just a collection update.

Any time new Mega-capable forms enter the legal pool, doubles teambuilding shifts quickly. Mega slots already shape speed control, defensive benchmarks, and damage planning in Champions, so Regulation Set M-C should affect both ladder preparation and tournament scouting. Expect early teams to over-index on the newly legal options while players test whether they are format-defining threats or just matchup picks.

The SP system also makes this worth watching closely. Since spreads are capped differently from mainline EV/IV building, a new Mega form can hit very specific bulk or Speed numbers without needing the same compromises players may remember from older formats. That can change how reliable common checks actually are.

Until full rule details and legality lists are available, the safest prep is to keep flexible answers to high-stat Mega attackers, prioritize consistent speed control, and avoid locking into teams that only handle the current M-C field.
