The card that Kaiba played in the manga was actually "Dark Energy". However, by the time this episode was aired in Japan, Dark Energy was already released in the OCG with its official effect. To avoid a conflict with the OCG, this card was specifically created to replace it.
On the first airing of this episode's dub, this card was erroneously given the same artwork as "Negative Energy". This error was later corrected on retransmissions.
