This is a quick reference for the rules when playing Domain Format, serving as an introduction. If you have any doubts or would like a complete and more detailed explanation of each rule, visit the other tabs.

• 1 Deck Master;

• 60 cards Main Deck;

• Up to 15 cards Extra Deck;

• There can be only one copy of each card in your Main and Extra Decks;

• All monsters in your Decks must belong to the Deck Master’s Domain.

• There are currently no banned cards.

  • That means you can use cards that are banned in the TCG/OCG.

  • You still have to follow the restrictions of the “Deckbuilding” section.

• A Deck Master’s Domain includes the following items, based on the Deck Master itself or mentioned in its effect:

  • Specific cards directly named (only the cards themselves)

  • Archetypes (including those belonging to mentioned cards)

  • Attributes (e.g. Fire, Dark)

  • Monster Types (e.g. Warrior, Dragon)
    

• A monster belongs to a Domain if it matches at least one of these.

• Your Deck Master (DM) starts in the Deck Master Zone (DMZ), a separate area from the field, hand, graveyard, and similar.

• While the DM is in the DMZ:

  • It cannot activate nor apply any of its effects.

  • It cannot be targeted or affected by other cards.
    

• A DM can leave the DMZ only through the following methods:

  • Being Normal / Tribute Summoned or Set;

  • Using its proper summon mechanic (ritual, fusion, synchro, xyz, link);

  • If it is a main deck monster, it can be pendulum summoned;

  • If it is a main deck pendulum monster, it can be activated as a pendulum spell;

  • Using its non-activating summoning method.
    

• After the DM moves to a different zone (except when being summoned), all effects are resolved, and just before the game state is open, each DM’s owner must decide whether to keep it in the new zone or return it to the DMZ.
  

• Summoning (or activating) your DM from the DMZ again costs an additional 500 LP for each time it has returned to the DMZ.

• Players make pairs sitting in front of each other.

  • Each pair shares the extra monster zones and the columns.

• Turn rotation moves clockwise.

• Priority sequence moves clockwise, starting from the turn player.

• The player going last in turn rotation gets the first battle phase of the game.

• If a player is removed from the game:

  • Sitting positions are not changed;

  • All their unresolved effects within the chain and cards they own will be removed from the game (except to tokens);

  • Any cards owned by other players will return to their opponents respective zone or sent to the grave if it is not possible.

• “Neither player” becomes “No player”;

• “Each player” and “both players” becomes “All players”;

• Continuous effect applies to all players/cards that meet the requirements (if any).

• For effects requirements that state “your opponent”:

  • When the condition doesn’t affect their resources, only one opponent needs to fulfill it.

  • Ignition effects need to target an opponent on activation.

• Triggers apply the opponent(s) that met its requirements.

• For effects with resource manipulation between players (eg. “Creature Swap”), each player performs the action in turn order starting with the turn player.
