Kite Tenjo's Decks

Kite plays a "Photon" Deck, focused on swarming the field with LIGHT-Attribute monsters, which he can then use to Xyz Summon his "Number" monsters and/or his ace card, "Galaxy-Eyes Photon Dragon". According to Mr. Heartland, Kite's Deck was made by him and Dr. Faker by using science from another dimension.

Deck
As "Galaxy-Eyes Photon Dragon" requires two Tributes of monsters with 2000 or more ATK, Kite includes cards which help him quickly fulfill that condition. His "Numbers" can be used for this purpose, or cards such as "Photon Spear", "Photon Thrasher" and "Photon Crusher". He also includes many cards which counter Xyz Monsters, such as "Galaxy Storm" and "Forced Release", as well as cards which counter Set cards, such as "Photon Cerberus" and "Photon Hurricane". In this way, Kite's Deck disrupts the opponents' current strategy, forcing them come up with an entirely new one.

Collected Numbers
Prior to his first Duel with Yuma, he had already collected eleven "Number" cards. As yet, it is unknown how many "Numbers" he possesses exactly, but after the mentioned Duel he was shown earning four more of them. Only five "Numbers" are known by name and it's unknown if he includes all collected "Numbers" in his Extra Deck.

Manga
Like his anime counterpart's, Kite's manga Deck is focused around swarm tactics in order to Summon stronger monsters such as "Galaxy-Eyes Photon Dragon" and "Photon Wyvern".
