In episode 146, Astral used this card during his Duel against Yuma Tsukumo. When "Future Number 0: Utopic Future" (whose ATK was 4000 via "Memories of Courage") attacks directly via "Memories of Courage", Astral activates this card to negate the attack and Special Summon this card as a Monster. 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 eight 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!" to double the ATK of "Utopic Future" and let it attack again. "Utopic Future" then attacks and destroys this card, winning Yuma the Duel.
