- While not mentioned on the card, this card's effect appears to be a Quick Effect, as Kalin was able to use it on his opponent's turn.
- Since it's stated by Yusei that Kalin Kessler no longer depends on "luck", one can assume that it was either discarded to the graveyard by the effect of "Infernity Zero" or sent by the effect of "Blaster Cartridge", since the other cards sent along with "Infernity Death Gunman" were never revealed.
- In episode 92, Kalin Kessler uses this card during his Ground Duel with Yusei Fudo against Lawton. This card was sent to the Graveyard at an unspecified point. Later the Duel is interrupted by Barbara and Lawton's henchmen, but Crow Hogan, Jack Atlas, and Sector Security arrive. Lawton activates an explosive to distract his enemies and escape, but Kalin catches up to him. The two of then decide to continue the Duel without Yusei and his cards. Lawton then activates the effect of "Blaster Ogre" to destroy "Infernity Doom Dragon" and inflict half its ATK as damage to Kalin, but Kalin activates the effect of "Infernity Des Gunman" and this card from the Graveyard. First Kalin activates the effect of this card to place it on top of his Deck. Next Kalin banishes "Infernity Des Gunman" from his Graveyard in order to activate its effect, negating the damage he would take and giving Lawton two choices. The first will allow Kalin to draw a card and reveal it and if it's a monster, Lawton will take damage equal to the damage Kalin takes and all effect damage Kalin takes this turn will be inflicted to Lawton instead. If it's not a monster, Kalin will take damage equal to the damage he took this turn. The second choice will allow Lawton to negate the effect of "Infernity Des Gunman", but Kalin won't take any effect damage this turn. Lawton chooses the first choice as he believes Kalin's top card to be "Blaster Cartridge", however Kalin reveals that his top card is this card. After he explains how it got on top of his Deck, the effect of "Infernity Des Gunman" activates, inflicting all damage Kalin would have taken to Lawton and winning Kalin the Duel.
