In the anime, this card has the effect of Thousand Knives.
The card's effect was further used wrong in the final duel between Yugi and Pegasus; Pegasus had his Relinquished equipped with Yugi's "Dark Magician" and a Jigen Bakudann on his side of the field. When Yugi played "Mystic Box", it freed "Dark Magician" from "Relinquished" and put "Jigen Bakudan" in its place.
