In the first above-mentioned episode, this card is shown in a flashback Atticus has when he explains to Jaden and his friends that this card is a card with his memories of Alexis in it. Atticus uses this card during his Duel against Alexis. He uses this card to Special Summon an unknown Normal Monster from his Graveyard. What happens next is unknown, but Atticus did win the duel.
In episode 173, Atticus uses this card during his duel against Yusuke Fujiwara. After he activates this card in order to revive "Red-Eyes B. Dragon", the effect of "Memory Snatcher" forces Atticus to declare what card he is targeting. Atticus is unable to remember due to Nightshroud making him forget what cards are in his Graveyard, but after Jaden and Jesse Anderson reach out to Atticus, Atticus regains his full memory on the cards in his Graveyard and declares that he is targeting "Red-Eyes B. Dragon" for this card's effect. Since the declared card was in Atticus' Graveyard, this card's effect continues. On Atticus' End Phase, this card's second effect destroys "Red-Eyes B. Dragon".
