In episode 181, Yami Yugi uses this card during his Duel against Dartz. He Special Summons this card via "Legend of Heart" along with "Legendary Knight Critias" and "Legendary Knight Timaeus". Yami Yugi then used all three knights to attack "Orichalcos Aristeros". The latter's ATK then became equal the ATK of the knights plus 300. All three attacks failed, but "Orichalcos Shunoros" lost 3100 ATK with each attack, eventually making the ATK of "Shunoros" 5900. "Shunoros" then attacks this card, but Yami Yugi uses this card's effect to activate the effect of the "Mirror Force" in his Graveyard, destroying all of Dartz's monsters and inflicting the ATK difference between this card and the destroyed monsters as damage to Dartz. "Mirror Force" is banished afterwards. Dartz then activates the last effect of "Orichalcos Shunoros" to summon "Divine Serpent Geh". Later "Divine Serpent Geh" attacks and destroys "Legendary Knight Timaeus", but Yami Yugi activates "Relay Soul" to prevent himself from losing by summoning "Dark Magician Girl". Dartz then activates "Impact Revive" to allow him to repeat his Battle Phase by Special Summoning "Timaeus" to Yami Yugi's side of the field with 500 more ATK. Dartz then uses "Divine Serpent Geh" to attack "Dark Magician Girl". In the next episode, Yami Yugi activates this card's effect to redirect the attack to this card. Yami then banishes "Obnoxious Celtic Guard" from the Graveyard so that this card gains its effects. This card is not destroyed by the attack since it had the effect of "Obnoxious Celtic Guard" and Yami Yugi did not lose the duel since "Dark Magician Girl" was still on the field. This card and "Critias" then attack "Divine Serpent Geh". Yami then uses the effect of "Critias" effect to activate the effect of the "Attack Guidance Barrier" in his hand, redirecting the attack to this card. Yami then uses the effect of this card to banish his three Magnet Warriors and redirect the attack back at "Critias" as well as multiply this card's ATK value by the number of monsters banished. Yami then uses the effect of "Critias" to redirect the redirected attack back to this card. This creates an infinite loop and allows Yami Yugi to activate the effect of "Legendary Knight Timaeus" to have it absorb the other Legendary Knights and Special Summon "Timaeus the Knight of Destiny". Later Joey uses this card in the battle against The Great Leviathan. It was brought out via "Legend of Heart" along with the other two knights. All the monsters that the three chosen Duelists summoned and brought out then attacked the Great Leviathan, but the attacks did not destroy it. When the Great Leviathan attacked, Yami Yugi had "Legendary Knight Timaeus" absorb the power of "Big Shield Gardna" in order to protect everyone. This saves the chosen Duelists and the three Knights, but every other monster that was summoned was destroyed. In the next episode, the chosen Duelists each summon out three new monsters. All the monsters that the chosen Duelists have then attack the Great Leviathan, along with the Duel Spirits that have come to aid in the fight, but the Great Leviathan still did not suffer any visible damage. The Great Leviathan than attacks, destroying all of the chosen Duelists' monsters, including the three Legendary Knights.
