The Mythical Cards, also known as the Legendary Cards (伝説のカード Densetsu no Kādo, lit. "Cards of Legend") in the anime, are eight special cards that contain the memories of legendary heroes and are the only force capable of stopping the Tree of Woe.
The Mythical Cards, except Arclight Ruler, were released in the Shadowverse card expansion Roar of the Godwyrm. They can be obtained in Shadowverse: Champion's Battle by purchasing the Mythical Battle Pass DLC or the Legendary Edition of the game.
History[]
The Mythical Cards were created by Leon Aurenche in order to use them against the threat of the Tree of Woe. However, the cards could only be used by Shadowverse players recognized by the cards.
Being unable to use or replicate them, Leon selected the seven protagonists to become the inheritors of these cards and use them to save the world. However, his true intention was for them to use the cards to defeat Eiji and the Empty Shadows so Leon could obtain the power of Nexus.
Seven of these cards were sealed in ruins throughout Nekome City, in hopes of the seven chosen ones becoming their owners. An eighth card, which Leon Aurenche intended to carry but failed to get chosen instead of its true destined owner, was recreated with part of its essence put into the Genesis Artifact card and the rest put into the AI of the Arc Autonomous Defense System, which would eventually become the being known as Arc Ruler.
After saving the world from Leon, the seven owners agreed to seal their Mythical Cards away due to their immense power. Wolfram Zerga helps them to seal the cards in statues erected on the Shadowverse College campus.
When the Arc Ruler begins his invasion of Nekome City, the owners attempt to revive the Mythical Cards to fight him off. However, Wolfram Zerga, who was actually Nexus' new vessel, destroys the Mythical Card statues with bombs, which was the true purpose of his gathering them at the school, so that they would not get in the way of the second coming of the Tree of Woe that he planned to bring.
The eighth card finally manifested through the Arc Ruler, going into Light's hands during his battle with Wolfram.
