Players may be required to register their decks and sideboards.
Registered decklists record the original composition of each deck and sideboard (if applicable). Once your decklist has been accepted by a Tournament Official, it may not be altered.
Players have the right to have access to see their decklist.
Decklist submission deadlines will be defined by the Tournament Organizer. By default, decklists are assumed to be due before the start of Round 1, but earlier deadlines may be defined by the Tournament Organizer.
