The "Void/jack" (ロストデッキ Rosuto Dekki) is a different deck from your main deck which replaces a player's main deck after the use of the "BeVoid/jack" ability of the "Void/jack DIMENSION or Jack DIMENSION" flag.

A Void/Deck consists of exactly 30 Void/Cards and only Void/ Cards (main deck cards cannot exist there). Void/ Cards can only be put into a Void/Deck, and cannot be put into the main deck due to their different backing.

When changing from the main deck to the “Void/jack Deck”, the normal cards in areas other than the deck area (i.e. the field, soul, hand, gauge and drop zone) remain as they are, and the fight continues with the Void/jack Deck placed in the deck zone as a new deck. For example, in the case of a "put a card from your deck into your hand" ability, when resolving this ability, one card is added from the current deck to your hand.

In areas other than the deck zone, it is possible that normal cards and Void/jack Cards are mixed together. For example, there may be a case where 3 normal cards and 2 Void/jack Cards are in your hand. For effects such as “drop one of your opponent’s gauge” or “choose a card from your opponent’s hand at random”, when choosing from a hidden zone where normal cards and Void/jack Cards are mixed, the cards must be chosen in a situation where it is possible to tell normal cards and Void/jack Cards apart.

It is not possible to mix normal cards and Void/jack Cards in the deck zone. For example, if an effect like "Overturn Ice Emperor, Miserea" or "Gate of Pardon, -Forgiven-" would return cards that originated from the main deck into the Void/jack Deck, main deck cards will not return and will remain there. Only Void/jack Cards will return to the deck. Another example, after placing the Void/jack Deck on the deck zone, and you use an ability such as “return a card from your gauge to your deck”, a normal card cannot be put into the current Void/jack Deck. If there are Void/jack Cards in the gauge, choose a Void/jack Card from the gauge and return it to the deck. If the gauge only contains normal cards, no card can be returned to the deck.

The Void/jack Deck may only contain a maximum of 4 cards with the same card name (excluding the buddy monster). Even if a card has a different ability or illustration, the maximum of 4 copies is kept. If a card effect states that "This card is also regarded as X", only the name printed in the name box will count towards the "max 4 copies" rule (See: Super Lethal Formation/Rulings). Both cards will have the same name, and are viable targets for any card that may support them.

You may only choose a Void/jack World monster as your buddy, only if you have the Void/jack World flag in your main deck. If you have the monster as your buddy, you do not flip over and reveal your buddy at the start of a fight. It is only flipped and revealed when your flag becomes the "Void/jack World" flag. During a fight, if the buddy is face down, it is not possible to buddy call, and the face down card in the buddy zone will be regarded as a blank card with no information.

If not otherwise specified, you cannot prepare multiple Void/jack Decks, and switch a different one for each match during the same tournament. When using card sleeves, it is necessary to use different sleeves for both your main deck and Void/jack Deck in order to tell them apart. When preparing for the game, the fighter using a "Void/jack Deck" must place it in such a way that it is visible to the opponent. It is highly recommended to place it on the right of the drop zone.

Tournament officials and judges may decide on the placement area of the Void/jack Deck, if it is deemed that there is insufficient space for it on the fight table. With acknowledgment from both fighters, a judge may rule for them to place the Void/jack Deck into a container such as deck cases or deck boxes, but care must be taken not to mix them up with other cards unrelated to the fight at hand. A fighter who wishes to use a Void/jack Deck must shuffle both the main deck as well as the Void/jack Deck during the preparation part before a game. After which, it will no longer be possible to check the contents of the Void/jack deck which has been removed from game.

The main deck removed from game, via the "BeVoid/jack" ability, is removed from the fight with all its cards face down and shall become a hidden zone. Both fighters will not be able to check its contents. During the fight, cards from the main deck that was removed from the game cannot be referenced, and cannot move to another area. Also, it is not possible to move any cards from any area to the main deck, which was removed from the game.
