Tamashi uses a Darkness Dragon World deck focusing on the Rebellion Dragon attribute. His main goal is to set five different Set spells on his field and win the game through his spell, ~Rebellion~. His deck runs a lot of defensive cards to keep himself alive while he slowly obtains the different cards needed to achieve his alternative win condition. Because of his view on fighting and violence, Tamashi refuses to attack with his cards or use any cards that destroy the opponent's cards.
