Howard X Miller

X (エックス Ekkusu) / Howard X Miller - Sartorius' lawyer, who dreamed of becoming a pastry chef when he was a child. In the Japanese version, he is instead a Pro League duelist associated with the Society of Light whose ranking is greater than Aster's. He successfully reduced the cards in Jaden's deck to zero, but lost when his own deck was exhausted. His name is meant to be a pun in English, as "mill" (a term borrowed from Magic: The Gathering) denotes a direct disruption of a player's deck.

[edit] Card list X plays a Deck Destruction deck. His strategy relies primarily on Monster Register, a card that, under normal circumstances would effectively demolish the decks of both players. X, however, cleverly protects himself with the ability of Trap Sluzer, while rendering himself almost untouchable with a wide array of Spells and Traps.
