In episode 64, Yusei uses this card during his Turbo Duel with Jack and Crow Hogan against Rex Goodwin. After he Normal Summons this card, Yusei tunes "Stardust Dragon" and "Stardust Xiaolong" with this card in order to Synchro Summon "Majestic Star Dragon".
In episode 79, this card appears in a flashback Crow has when he notes to Jack that by defeating Goodwin they were able to unite New Domino City and Satellite.
This card also appears in a flashback Yusei has when he notes that he won't be able to defeat Ghost and his "Meklord Emperor Wisel" if he can't go at an incredibly fast speed that would allow him to Accel Synchro Summon.
This card does not appear to be a part of the characters' decks in the anime, instead it simply appears on top of the player's deck when the "Crimson Dragon" decides that they (or their opponent in the first two cases) need "saving" and goes away when the Duel is finished.
In the anime so far, when Jack and Yusei have used this card, all of the Mark of the Dragons vanish and reappear as the full mark on the back of the player that is using this card.
