Reginald plays an Xyz WATER Deck[1] consisting of monstrous looking sea creatures such as various races of sharks and arthropods. His nickname is "Shark" and is derived from his Deck theme and his previous brutal nature. Reginald acquired his Deck from his father at a young age.[2]
Shark's Deck now focuses more on Rank 5 Xyz Summons, primarily his newly acquired "Numbers" through cards such as "Edict of Atlantis" and "Depth Shark:. He also uses a multitude of cards to negate attacks such as "Hide and Shark" and "Deep Current".
