- In episode 177, Yami Yugi uses this card during his Tag Duel with Kaiba against Dartz. He summons this card via "Black Luster Ritual". On Yami Yugi's next turn, he activates "Polymerization" to fuse this card with Kaiba's "Blue-Eyes Ultimate Dragon" in order to Fusion Summon "Dragon Master Knight". In the next episode, "Dragon Master Knight" attacks directly via "Reflect Energy", but Dartz activates the effect of "Orichalcos Deuteros", Tributing "Orichalcos Gigas" to destroy "Dragon Master Knight". Yami Yugi then activates "De-Fusion" to return "Dragon Master Knight" to the Extra Deck and Special Summon this card and "Blue-Eyes Ultimate Dragon" from the Graveyard. This negates the effect of "Orichalcos Deuteros" since its original target had been removed from the field. Later two of Dartz's Mirror Knight Tokens attack this card and "Blue-Eyes Ultimate Dragon". Due to the effect of the tokens, their ATK becomes equal to the ATK of the monster they are battling during damage calculation only. Dartz then removes the Shield Counters on the attacking tokens to prevent their destruction, so only this card and "Blue-Eyes Ultimate Dragon" are destroyed.

Since all three of Yugi's chosen monsters were stronger than all of Jaden's chosen monsters, all of Jaden's chosen monsters are sent to the Graveyard and he takes 1500 damage (500 for each monster sent to the Graveyard) while all of Yugi's chosen monsters are added to his hand.
