Can a player view their decklist during the event?

A player can view their decklist during the event as long as the list is not altered. The rules permit players to reference their own decklists to ensure that they are playing with the correct cards. Having access to their decklist helps players confirm their strategy, double-check card counts, and verify that their sideboard matches their initial registered list.

This ability to consult their own decklist is important for maintaining the integrity of the game and ensuring that players are aware of their own deck compositions. However, players must not change their decklist in any way after submitting it before the event starts, as doing so would violate tournament rules and could lead to penalties.

The other options imply restrictions or prohibitions that do not align with the current tournament regulations, which support the player’s ability to manage their deck effectively within the boundaries of what is deemed fair play.
