What should players do if they notice a mistake in the tournament procedure?

Players should report any mistakes in the tournament procedure to a judge immediately because it ensures that the issue can be addressed properly within the context of the official rules and guidelines of the tournament. This action is essential for maintaining the integrity of the event and allows judges to manage the situation effectively according to the Magic Tournament Rules (MTR).

When a mistake occurs, it could potentially affect the outcome of the match or the tournament as a whole. By notifying a judge, players help ensure that appropriate steps can be taken to correct the mistake, such as reversing a game state or addressing any procedural errors. This approach also helps maintain a fair competition and transparency among all participants.

Engaging in discussions with other players or attempting to resolve the matter privately does not adhere to the structured nature of tournament play and could lead to misunderstandings or further complications. These actions may also deny the judges the opportunity to apply their expertise to resolve the situation according to the best practices established by the tournament rules.
