Kalin Kessler's Decks

In his early days, Kalin's Deck focused mainly on Fiend-Type monsters that had low levels and high attack points. 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 "One-Hundred Eye 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.

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 he has 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 on his own.
