6.1. Constructed Formats
The V:EKN sanctions only one constructed format: Standard Constructed.
6.1.1. Set Restrictions
The tournament organizer may limit players to the use of one or more card sets. For example, the tournament organizer may require players to restrict their decks to cards from the Dark Sovereigns and Final Nights card sets. The tournament organizer must advertise any card set restrictions prior to the event. All cards will be required to use the most recent card texts even if the revised card text appears in a set not allowed in the current event. Example: In an event restricted to the use of the V:TES base set, the Master card "Misdirection" would still lock only one minion.
Note: Sanctioned tournaments conducted with card set restrictions will not have their results included in the V:EKN player ratings.
6.2. Constructed Deck Size Limits
Standard Constructed decks must contain a minimum of sixty cards and a maximum of ninety cards. The crypt must contain a minimum of twelve cards.
6.3. Constructed Deck Registration
The head judge or tournament organizer may require players to register their decks upon arrival at a tournament. Registration records the original composition of each deck. Once a tournament official receives a player's decklist, the deck may not be altered. Failure to properly register a deck will result in the head judge applying the appropriate provisions of the V:EKN Penalty Guidelines. The V:EKN recommends that organizers check a reasonable number of decks against their decklists each round.
