What is the significance of “deck registration” before a tournament begins?

The significance of deck registration before a tournament begins primarily lies in ensuring transparency and reducing the likelihood of cheating. By requiring players to present their decks, tournament organizers can verify that the deck a player plans to use in competition matches the list they registered. This process helps maintain the integrity of the tournament environment by deterring players from switching cards or making alterations during the event. Deck registration creates a standard that everyone must follow, enhancing the overall fairness of the competition and helping to uphold the spirit of the game.

The other options, while they may seem relevant, do not capture the core purpose of deck registration. For instance, allowing players to trade cards, informing players about new releases, or determining seating arrangements are not functions served by the deck registration process. Instead, the primary focus is ensuring that each participant adheres to their registered deck, promoting fair play throughout the tournament.
