After acquiring "Neo Galaxy-Eyes Photon Dragon", Kite started to use more Level manipulation cards such as "Shift Up" as well as cards to gather its Xyz Materials more easily through cards like "Photon Caesar". In addition, he utilizes the "Galaxy" archetype to further assist in Summoning his newfound power.
Prior to his first Duel with Yuma, Kite had already collected eleven "Number" cards.[3] After the mentioned Duel he was shown earning four more of them: one from Fortuno,[4] two from 2 other holders,[5] and one from Cinco.[6] Only five were known by name and it's unknown if he included all of them in his Extra Deck. He eventually lost all of his "Numbers" to Vetrix.[7]
