Tetsu Trudge's Decks

Tetsu Trudge first plays a Guard Deck themed around his occupation as a security officer. He uses security-related cards such as "Handcuffs Dragon" and "Wiretap" to limit what his opponent is able to do. He also carries a trump card in the form of "Montage Dragon," which he can bring out as a heavy hitter if the aforementioned strategy fails. As seen in several flashbacks, where Security officers use Montage Dragon and Assault Dog (seperate flashbacks), it can be assumed every Security officer got this deck.

Trudge received a new deck from the Bureau for a rematch with Yusei. This deck is a Pursuit Deck relating to his goal of blocking the pipeline so Yusei cannot get through. Its prominent cards include "Gate Blocker," which stops the opponent from using "Speed World," and "Gonogo" which automatically flips the monster it's battling into face-down Defense Position. His strongest card is "Goyo Guardian," which can resurrect the monsters it destroys as defenders for Trudge. This type of deck is also commonly used by other Security officers. They probably got their deck changed at the same time Trudge got the new deck.

As a Dark Signer, Trudge's Deck became a Mill Deck that uses "Worm" monsters and the powerful Dark Synchro Monster "Dark Diviner" whose effect can not only mill his opponent's deck, but render itself and its user almost invincible.

During the Third Season, in his duel against Ghost his deck appears to be the same, though in his duel against Aki during the license exam his deck has changed into a "Stygian" deck that utilizes cards that can damage, overpower and lock his opponents.
