Kite Tenjo's Decks

Season 1
In the anime, Kaito's Deck focuses on the LIGHT-Attribute to swarm monsters, which he can then use to Xyz Summon his "Number" monsters. Using them and other powerful monsters, he can bring out his ace card, "Galaxy-Eyes Photon Dragon". His Spell and Trap line-up focuses swarming and on preventing the dangers his opponent's Spells and Traps pose. Most of his cards are part of the Photon archetype. According to Mr. Heartland, Kaito's Deck was made by him and Dr. Faker by using science from another dimension.

Collected Numbers
Prior to his Duel with Yuma, he had already collected eleven "Number" cards, but after defeating Jin, he earned 1 more, possessing twelve. Only four of them are known by name and it's unknown if he includes all collected "Numbers" in his Extra Deck.

Manga
In the manga, Kaito's deck has a similar strategy to his anime one, consisting of Photon and Light Support Cards.
