When Kalin was in The Enforcers, he used a beatdown Deck consisting of high ATK, Level 4 Monster Cards to quickly overpower and punish the opponent. He used this Deck when The Enforcers took over Satellite by destroying other Duel Gangs with it. These events were shown during flashbacks in the Dark Signer arc. This Deck was taken from Kalin when he was arrested.
In Crash Town, Kalin continues to use an "Infernity" Deck focused around his famous "handless combo", though he Duels in Ground Duels this time. He utilizes several cards which revive the "Infernity" monsters from the Graveyard, making full use of their capabilities. He also uses several burn cards such as "Infernity Burst" and "Infernity Randomizer" which work well with his overall strategy of swarm and need for cards to be in the Graveyard respectively.
