Reginald Kastle's Decks

Anime
Reginald plays a WATER/Fish Deck consisting of monstrous looking sea creatures such as various races of sharks and arthropods. He utilizes a Burn strategy in order to quickly gain the advantage through cards such as "Submersible Carrier Aero Shark" and "Explosive Urchin", with a focus on using Level 3 monsters to Xyz Summon Rank 3 Xyz Monsters. After his loss to Yuma he modified his deck to counter the "Numbers" by negating their effects with "Black Ray Lancer" or taking control of them. His ace monster is "Black Ray Lancer".

Manga
Ryoga's manga Deck is, so far, identical in appearance and function to his anime Deck, having the same strategy.
