401. Deck Registration

401.1. Players in competitions are required to register their decks and sideboards (if applicable to the format) at high OPL.
401.2. A registered decklist must have a complete, unambiguous record of the player's Champion Legend, battlefields, Main Deck including Chosen Champion, Rune Deck, and sideboard (if applicable to the format).
401.3. Once a decklist has been registered and delivered to a competition official, it can't be changed.
401.4. In a constructed event, a player's deck must be registered prior to the start of the first round of competition.
401.5. Other player's decklists are normally considered private information. The head judge of an event may run that event or the final rounds of that event using an open decklist policy. In this case, all players' decklists will be considered public information.
