In episode 146, Astral used this card against Yuma Tsukumo. When Yuma attacked Astral directly with "Number F0: Utopic Future" by the effect of "Memories of Courage", Astral activated this card, summoning it as a monster and negating "Utopic Future's" attack. Upon seeing this card's form, Yuma is reminded of his first encounter with The Door, whose voice soon began to speak and remind him of its prophecy: Whoever opened The Door would be rewarded with great power, but would need to sacrifice the most important thing to him, and Yuma realized that, if he did open The Door, he would lose Astral forever. Astral explains that if Yuma does not destroy this card, Yuma will lose on the next turn, because on Astral's Standby Phase, he could banish all 8 of his "Number" monsters from his Graveyard and inflict 4000 damage to Yuma (500 damage per banished monster). Yuma is hesitant to use the last card in his hand, but Astral urges him to face the future with courage, saying that that card could change the outcome of the Duel, and thus, determine their destinies. Inspired by such words and with a heavy heart, Yuma activates "Double or Nothing!", which, since "Utopic Future's" attack was negated, allowed "Utopic Future" to attack again with its ATK doubled, from 4000 to 8000. "Utopic Future" then attacks and destroys this card, winning Yuma the Duel.
