Paradox uses this card during his Duel against Yugi Muto, Jaden Yuki, and Yusei Fudo. He Special Summons this card via "Malefic Paradigm Shift". On Paradox's next turn, "Malefic Red-Eyes B. Dragon" attacks "Dark Magician Girl", but Jaden activates Yugi's "De-Fusion" to return "Elemental HERO Neos Knight" to the Extra Deck and Special Summon "Elemental HERO Neos" and "Junk Gardna" from the Graveyard. Yusei then activates the first effect of "Junk Gardna" to switch "Malefic Red-Eyes B. Dragon" to Defense Position. "Malefic Blue-Eyes White Dragon" then attacks and destroys "Dark Magician". This activates this card's first effect (which will destroy all monsters Yugi, Jaden, and Yusei control and inflict 800 damage to them for each monster destroyed this way), but Yusei Tributes "Stardust Dragon" to negate the effect of this card and destroy it. Paradox activates this card's second effect to banish "Malefic Rainbow Dragon" from his Graveyard and prevent this card's destruction. This card then attacks and destroys "Neos". This activates this card's first effect, destroying all monsters Paradox's opponents control and inflicting 800 damage to them for each monster destroyed this way. With two destroyed this way, Yugi, Jaden, and Yusei take 1600 damage. On the last turn of the Duel, "Stardust Dragon" (whose ATK was 10,000 due to "Neos Spiral Force" and "Dark Spiral Force") attacks and destroys this card, winning Yugi, Jaden, and Yusei the Duel.
