The Hall of Fame (殿堂入り) is the list of cards that either cannot be played in a deck, or are restricted to a certain amount.

TCG Banlist

There is nothing restricted in the English game of Duel Masters. However after its release, Bombazar, Dragon of Destiny was placed on a "watch list" by Wizards of the Coast. Due to the game being discontinued in the TCG, there is no official restriction.

OCG Banlist

This is the current list of banned or restricted cards in Japanese play. Also, all decks must be 40 cards, unlike the TCG where 40 is simply the minimum amount.

Disabled cards

You cannot have any copies of disabled cards in your deck. These cards are distinguished from the Premium Hall of Fame by being never usable at any point in time in the OCG and by being banned for reasons other than being overpowered.

Duo Premium Hall of Fame

Pairs of cards in the Duo Premium Hall of Fame cannot both be used in a deck at once. If a deck has one of the cards of the pair in it, it cannot use the other card.

Currently, there are no pairs of cards in the Duo Premium Hall of Fame. Romanesk, the Dragon Wizard + Crest of Mother and Romanesk, the Dragon Wizard + Soulswap are the only pairs of cards to have held a place here.

Hyperspatial Premium Hall of Fame

This is differentiated from the Duo Premium Hall of Fame in that one of the cards involved is a psychic creature. If you have one of the cards in your deck, you cannot have the other in your hyperspatial zone. If you use one of the cards in your hyperspatial zone, you cannot use the other card in your deck.
