On a downtown street corner, there exists an unusual card shop. This shop produces cards imbued with unique powers. Creature cards, magic cards, ritual cards, venue cards, temporary cards... Within its walls, one can find enigmatic magic, intricate equipment, fearsome creatures, and even ancient legacies, all manifested as cards. Undead, feral beasts, dragons, ancient lizards... The cards encompass the might of creatures from various races. It is rumored that only top-notch players receive an invitation from the owner to ascend to the second floor. Likewise, only formidable believers can genuinely wield the power to command the cards. "Welcome to my card shop, I am the owner Fang Tian."
