Yu-Gi-Oh Starts with Sending Card Sets

Yu Xiu traveled through time, bringing with him an "infinite card library" that can take out all the cards. From then on, the god of sending cards appeared. Are there too many pig teammates in the late stage of GX? Send several sets of hero cards to the ten generations, allowing him to embark on the path of growth as both a hero and a villain. Don't have a good card in the satellite area? Shock! Overnight, a set of useless two appeared in the place where Fudo Yusei picked up the cards! Is the time traveler stuck? Don't be afraid of the kids! Lao Xiu has given you a deck of cards! "How many decks do you want to give away?" "Unlimited sets." "Then what do you use yourself?" "It depends on your mood." This is just a story about playing cards, sending cards, and a group of people whose destinies were changed by time-travelers. PS: Some villains in GX and most villains in 5Ds will be strengthened, not just beating up primitive people. And after each small chapter ends, the real-life development will be written.
