Pokémon Champions Global Challenge I rules use Regulation Set M-C and the Double Battle format. Pokémon directs players to the in-game news for the complete list of eligible Pokémon, ranking information and detailed competition regulations.
The broad rules are simple enough to understand before entering, but the in-game event notice remains the final check before registering a Battle Team. That matters because the tournament team is chosen during sign-up.
Pokémon Champions Global Challenge I rules: the confirmed format
Pokémon Champions Global Challenge I rules are built around Double Battles rather than Singles. Team preparation should therefore account for two active Pokémon, partner interactions and the specific legal roster in Regulation Set M-C.

The official event page does not reproduce every eligible species and restriction. Instead, it points players to the competition news inside Pokémon Champions for the full list.
Regulation Set M-C applies
Pokémon Champions Global Challenge I rules use the current M-C ruleset for the competition. The Click already covers the Regulation M-C roster, items, moves and team ideas separately, but the event notice in the game is the final authority for this tournament.
Checking legality immediately before registration is especially important for players reusing a Ranked Battle team, because an online competition may apply event-specific settings alongside the named regulation.
Battle Team registration
Pokémon Champions Global Challenge I rules require a Battle Team to be registered during sign-up. That team is the one attached to your event entry, so do not rush through registration with an unfinished test team selected.
The competition can be joined after it starts, which gives late entrants time to prepare. It does not change the fixed event end time, so late players have a smaller battle window.
Reward rules are participation based
Pokémon Champions Global Challenge I rules set the Archaludon requirement at three or more completed matches with a win or loss. The reward condition is therefore not tied to three wins or a particular ranking position.
After the event, players must check their ranking result in Online Competitions before claiming Archaludon from the mailbox. That post-event step is part of the published distribution process.
Championship Point eligibility
Pokémon Champions Global Challenge I rules also sit inside the 2027 Championship Series. To earn Championship Points, the Trainer Central account has to exist before registration and be linked through Play! Pokémon Access.
The Pokémon Champions Support ID must be entered in the app, and the links need to stay active until rewards are awarded. Players not pursuing points can still enter without this setup.
Where to verify last-minute changes
Pokémon Champions Global Challenge I rules should always be checked in the in-game news before the Battle Team is registered. The web article provides dates and broad format, while the game carries the detailed eligibility information.
If a Pokémon, form or team element is rejected by the event, treat the live in-game competition rules as authoritative rather than forcing an older team list to fit.
How to use the rule information safely
The named regulation and battle format are enough to explain the event at a high level, but they are not a substitute for the live legality screen. Pokémon deliberately directs competitors back to the in-game news for the complete eligible list, which can include details that are awkward to reproduce reliably in a static article.
That means a team guide should be treated as preparation, not proof of legality. Before registering, verify every Pokémon and the team configuration against the event notice shown by the current client. If the game rejects something, the live competition rule takes precedence over an older screenshot, cached search result or third-party list.
The three-match Archaludon threshold also does not change the ruleset. A player still has to enter valid Double Battles under M-C; the participation prize simply does not demand a winning record.
For players mainly interested in the participation distribution, the rules still matter even though the reward does not require wins. An invalid team cannot become a valid event entry simply because only three completed results are needed. Build or select a legal M-C roster first, then treat the three-match threshold as the reward condition after entry rather than as a shortcut around tournament legality.

Pokémon Champions Global Challenge I rules are straightforward at the top level: Regulation Set M-C, Double Battles and a registered Battle Team. The most important habit is checking the in-game competition notice before locking the team, because that is where Pokémon places the complete event detail.
