Arrathir Quinn, a young Magic player goes on the search for a card shop that supposedly sells Alpha (the first Magic set ever printed) boosters. He wanders into the YGO-verse by way of a rip in the fabric of the Multiverse and meets Yūgi and Jōnouchi. They create a blended version of the Magic and Duel Monsters rules and Arrathir duels Yūgi and Kaiba, beating them both. Afterwards, Arrathir and Yūgi meet Khell Dracos, a summoner from Dominaria. Yami no Marik returns and Khell teaches Arrathir how to summon. A few days later, Khell leaves for Dominaria and Arrathir returns home the next day.
