Game Original Card

Game Original Cards are cards that are exclusive to the Duel Masters Video Games.

Details
Each of these cards don't have a physically released card (with the exception of Galberius Dragon). However, Galberius's original printing had a red card back and was considered a Disabled Card, unable to be used for official tournament events.

They also feature races not appearing in the Trading Card Game, with Holy Dragon and Cyber Dragon (appearing before Light and Water first had dragon races in DM-22 The Dragonic Nova).

Some of them feature randomly calculated abilities not possible in the physical Trading Card Game.

There is a game original keyword of "Hunter", where a creature automatically wins a battle against a specified race of creature.

In 2012, Takara Tomy announced that they are withdrawing for the Video Game industry, so no future game original cards will appear.
