- In episode 177, this card can be seen in Seto Kaiba's hand during his Tag Duel with Yami Yugi against Dartz. In the next episode, Kaiba activates this card to Tribute his "Blade Knight" and allow Yugi's "Dragon Master Knight" to attack directly this turn. "Dragon Master Knight" then attacks directly, but Dartz activates the effect of "Orichalcos Deuteros" to Tribute "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 "Blue-Eyes Ultimate Dragon" and "Black Luster Soldier" from the Graveyard. This negates the effect of "Orichalcos Deuteros" since its original target had been removed from the field.
