I'm playing cards in Duel City

Su Yu, who created a trumpet in the fully submersible trading card game "Yu-Gi-Oh: Linking the World", inexplicably traveled through the game world, and even brought his own NPC template.
Time went back to the time before the game was launched, the player still had a month to come, the nameless Pharaoh was still sleeping in the body of the high school student Muto Game, and the duel city with cross-generational significance had not yet started.
When the game officially launched, players logged in and found that there was a new NPC in the game that was not in the original game.
Su Yu: Do the players over there want to draw card packs? 51 packs, five hundred and ten companies, the price is fair, no one is cheating!
The players stared directly at the pot of lust marked as UR in the product list, their eyes were burning, and the same thoughts came into their minds—
- Just draw that card!
