Fantasy Card Duel, My Cards Can Be Infinitely Changed

This is a world where fantasy card masters use fantasy cards to fight. Every illusion card master has a leader card that he is passionate about, and leader cards are the core of the deck construction. While everyone was debating which deck was the strongest, Lin You silently looked at his leader card named Alice. Necromancer Alice: Oh, today I learned how to summon the undead! As a result, Lin You's deck became an undead deck that mainly focused on spreading the field. Swordsman Alice: Hehe, I will personally participate in this game! So Lin You had to use a Kendoji deck that focused on direct damage. Puppeteer Alice: That's incredible! Alice is attracted to the card opposite! Under the horrified gaze of his opponent, Lin You silently changed his deck to the Minotaur deck. "Hey! You don't want to bully my card!" "Lin You, you guy! How many leader cards do you have! Why do you use different decks every time!" "Sorry, I only have one leader card. But my leader card seems to be able to..." "Infinite variations!" Even the five-star fantasy card master Mike Thurser had to make an evaluation. It was not that the strongest deck fell into Lin You's hands, but that whichever deck Lin You used was the strongest deck! ———— Original cards, Yu-Gi-Oh! Rules
