Card Trivia:Overlord of the Lost Vault


 * This card has the same Attribute, Rank, Type, ATK and DEF as the other "Lost Vault" Xyz Monster, "Tyrant of the Lost Vault".
 * Strangely enough, this card artwork looks much closer to "Warrior of the Lost Vault" other than "Tyrant of the Lost Vault".
 * This card's original idea was to become a Timewarp Impure Monster, but the idea was scrapped and changed into an Xyz Pendulum Monster for two reasons:
 * It is not sure if Timewarp Impure Monsters would exist, as it was not confirmed by Nova about whether custom mechanics will have "Impure" forms and under which circumstances.
 * It fits better, as the ace card that the user of the "Lost Vault" archetype uses in Yu-Gi-Oh! Apocalypse is "Tyrant of the Lost Vault", the only Xyz member of the archetype, thus it fits better to have an "Impure" evolution.
