Joey Wheeler 11-12 Lose

During Duelist Kingdom, Rex's Deck contains an assortment of Dinosaur-Type monsters, his most powerful cards being the Dragon-Type "Serpent Night Dragon" and "Red-Eyes B. Dragon", both of which are also his rarest cards. His style of Dueling is simple, relying on the brute power of his Dinosaurs augmented by the Dueling field to strengthen them.

Anime Deck - Season 1

Battle City

Opponent(s) Episode(s) Outcome
Espa Roba 58 Lose

Although Rex wasn't seen Dueling, he was shown losing to Espa Roba, losing his ante of "Serpent Night Dragon", his rarest card in his deck.

Waking the Dragons

Opponent(s) Episode(s) Outcome
Gurimo 145 Lose (w/Weevil Underwood)
Joey Wheeler 160-162 Lose

In Waking the Dragons, Rex uses a Dinosaur Deck heavily focused on swarm tactics. In addition, he utilizes the "The Seal of Orichalcos" to turn normally weak monsters into powerful beatsticks. Echoing of his earlier Deck, Rex's strongest monster is not a Dinosaur, but the Dragon-Type "Tyrant Dragon".

KC Grand Championship

Opponent(s) Episode(s) Outcome
Zigfried Lloyd 189 Lose (w/Weevil Underwood)
Weevil Underwood 224 Not shown

Not much of Rex's deck was shown in this arc, but presumably, it was yet another Dinosaur Deck.
