How Is Grail A Not a Grail?

[Welcome to the world of Yu-Gi-Oh! roguelike.] [In this world, the awakening of the Creator Dragon from its eternal slumber has caused all kinds of chaos. You will travel the world as an alchemist, searching for a way to save it.] [During your journey, you will borrow the power of past Duel Kings to gather materials, then use alchemy to turn them into cards. Finally, build your own deck and defeat the Creator Dragon in a final duel to save the world!] You Du: “So here’s my question: why did you send me to the Nasuverse to take part in the Holy Grail War?” Although the System had given him the alchemy to craft Yu-Gi-Oh! cards from all kinds of materials, based on the game’s setting, he was still just an ordinary card game nerd who couldn’t fight his way out of a wet paper bag. How was he supposed to stand up to those cheaters who could carpet-bomb the battlefield with beams of light? Obviously, he’d change jobs on the spot and become a summoner, summon Duel Monsters to gang up on his opponents, and unleash a barrage of magic and traps himself! By the way, you just summoned five skeleton soldiers, right? Whoa, here comes the meteor!
