Kalin Kessler's Decks

The Enforcers
In his early days, Kalin's Deck focused mainly on Fiend or Beast-Warrior-Type monsters that had low Levels and high ATK such as Vorse Raider.

Dark Signers
After becoming a Dark Signer, and with the loss of his own Deck, his Deck changed to becoming an Infernity Deck, which focuses on the use of his Dark Synchro Monster "Hundred-Eyes Dragon" and its ability to use the effect of any DARK monster in his Graveyard when it's face-up on the field, primarily those of the "Infernity" series, which gains effects when the player has no cards in his hand. Kalin's "Earthbound Immortal" monster is "Ccapac Apu", which is also his ace monster, taking advantage that in a Turbo Duel, "Speed World" is always active adding the effect of "Ccapac Apu" making his "Earthbound Immortal" invincible against spells, traps, and monster attacks.

Crash Town
During Season 2 he still plays with the Infernity Deck, but he has new support now which seemed to make it better and faster. The reason for this is that since Kalin had his own deck taken away by Sector Security, if he never got it back, then the Infernity cards would be all Kalin had left. In a sense, the Infernity cards, with their powerful effects and chancy condition (only able to use their effects while the controller has no hand) are symbolic of Kalin's situation: he has nothing left to live for, as he's already powerful being on his own. His deck also takes on a more Western theme as reflected in some of his new cards.

Manga
In the Manga, Kalin continues to use his famous Infernity Archetype, but they are based around a medival theme such as knights instead of on a western theme. He also uses an array of Purgatory traps which aim to seal off the opponents Attacks and Effects.
