Yu - Gi - Oh ! Ultimate Masters : World Championship Tournament 2006 Yu - Gi - Oh ! Ultimate Masters : World Championship Tournament 2006 , known as Yu - Gi - Oh Duel Monsters Expert 2006 「 遊戯王デュエルモンスターズ エキスパート2006 」 in Japan , and Yu - Gi - Oh World Championship Tournament 2006 in Europe is a video game released in early Summer 2006 based on the " Yu - Gi - Oh ! " franchise . The gameplay involves the player collecting cards in - game and using them to battle the computer players . Players may also ( upon completing the Free Duel mode ) battle against Decks which they themselves have designed and saved . This game comes with three promotional Yu - Gi - Oh ! cards enclosed ; they are " Helios - The Primordial Sun " , " Helios Duo Megistus " , and " Golden Homunculus " . These cards were later handed out in English Blister Pack s . This game contains every Yu - Gi - Oh ! card made in English at the time of its release , with the exception of " Barrel Behind the Door " , " Darkness Approaches " , " Double Spell " , " Dragon Piper " , " Gravekeeper ' s Chief " , " Kaiser Colosseum " , " Mind Crush " , " My Body as a Shield " , " Spring of Rebirth " and Level 5 Normal Monster s other than " Aitsu " , " Bottom Dweller " , " Curse of Dragon " , " Giga Gagagigo " , " Illusionist Faceless Mage " , " Jack ' s Knight " , " Kabazauls " , " King of Yamimakai " , " Labyrinth Wall " , " Molten Behemoth " , " Mr . Volcano " , " Ocubeam " , " Steel Ogre Grotto # 1 " , " Terrorking Salmon " , " The Earl of Demise " and " Woodborg Inpachi " . Unlike previous games , the cards collected from packs have direct correlation to those released for the TCG . Players purchase packs from the original " Legend of Blue Eyes White Dragon " all the way up through the " Shadow of Infinity " series . There are also specialized packs focusing on themes ( Machine s , Spellcaster s , Warrior s , etc . ) , and even by card type ( all Effect Monsters , all Normal Monsters , all Spells , all Traps ) . Additional packs are unlocked as you progress in the game . " Elemental Hero Neos " is featured in the game prior to its release . As with prior games in the series card passwords printed on TCG cards can be entered in order to obtain cards in the game . You can now get as many copies of each card as you want in this way ( limited to one in previous games , except " WCT 2005 " ) , but you must pay a fixed cost for each card ( costs range from a few hundred DP to in excess of 10000 DP for Limited and Forbidden cards such as " Pot of Greed " and " Black Luster Soldier - Envoy of the Beginning " ) . Also note that although link Duels are still possible , trading cards between games is not . Also different from the previous videogames , this one does not pit you against characters from the anime and manga ( and their known Decks ) . Instead , you Duel against the various ' monsters ' and Decks built around them ( Kuriboh , Dark Magician , Cyber Dragon , etc . ) . The monster Duelists are organized into five different tiers , with each tier getting unlocked as the game progresses . There is also a special tier where you can Duel yourself ( the opponent uses your currently selected Deck ) , and Copycat ( who uses a Deck of your choice from one of up to 60 of your saved Deck builds ) . Besides the free Dueling , there are also Challenges . These consist of Duel Puzzles ( winning a Duel given certain cards on the board and in hand ) , Themed Duels ( full Duels based on a certain theme for building your Deck ) , and Survival Duels ( see how many Duels you can win in a row with your Life Points carrying over from Duel to Duel ) . As you complete certain percentages of challenges , more packs and Free Duel Duelists are unlocked . You can also update the Forbidden / Limited List to the current one at the Yu - Gi - Oh ! Card Game Website .
