Yu-Gi-Oh! Virtual World gameplay

During the Virtual World Arch, the The Big Five forced the Duelists aboard Kaiba Craft 3 into their own tournament. The Battle City Rules were used, with the modification of a Deck Master. The deck master was an extra card that gave Continuous Effects to the field of the player who controlled them. They could be special summoned in their regular monster form, but if they were destroyed while on the field, the player would lose automatically. Deck Masters could be changed, if they are tributed for an effect, or if they are used as a Fusion Material Monster, the fusion monster is then treated as the Deck Master. Once on the field, The Deck Master cannot be returned to the Deck Master Zone.
