His Decks usually revolve around the "Warrior" series. People who know him very well (such as Jack, Kalin and Crow) say that he is starting to get predictable because he has been using the same basic strategies for a long time. Despite this, Yusei is still known for his genius dueling style, of being able to quickly comprehend his opponent's tactics and quickly formulate an effective counter strategy.
With his own, Tanner and Yanagi's cards confiscated, Yusei assembled a Deck using random cards given to him by other inmates at the Facility to use in his Duel with Mr. Armstrong. This Deck's card count adds up exactly to 40 cards. Most of this Deck's cards feature criminal-like monsters or other shady cards. This Decks' contents were given back to their owners once Yusei defeated Mr. Armstrong.
Ever since Season 1, Yusei's ground Deck has gained quite an array of different cards. He now uses the Bike series as well as a new selection of Synchrons and their Warrior counterparts. He also received a selection of new Traps which negate damage or opponents monsters effects. With this Deck Yusei was not only able to stop Luna, Leo and their classmates from getting expelled, but he managed to save his life as well as Lazar's by defeating the Guard Robot and managed to gain allegiance with Sherry LeBlanc and Elsworth by defeating him in a Duel and gaining his respect.
Within the manga, Yusei's Deck is based more around the "Junk" archetype than his anime counterparts. He also uses various other Monster Cards which have appearances of tools or Warriors. He also uses an array of synchro warriors much like his anime counterpart but these ones don't require specific tuners.
