Kazuo Abe

Yutoku Abe (安倍尤徳 Abe Yuutoku) is the protagonist of 48 Days. His initial epithet is "The Rookie" due to his lack of Style, however, after conquering the Earth domain, it becomes "The Miracle".

First concept
Yutoku runs an Honor Deck, composed of only small monsters. This deck reflects the meaning of his name which his father gave to him, representing how Yutoku believes that he's weak, but even so he can live with honor.

Yutoku uses extremely versatile tactics, using his low-Level monsters for stalling or getting rid of the opponent's monsters with varied effects. He also uses many cards such as "Double Spell" and "Formula Statue" to re-use the opponent's cards, adding even more versatility to his combos.

Update: Alternative idea - a deck focused more on the cards like "Magical Trick Mirror", "Double Spell" and "Formula Statue" that uses the opponent's weapons against them.
