In the near future, the national immersive online game "Ten Thousand Cards League" will replace traditional e-sports. The game combines MOBA battlefields, card construction and city leagues. Professional players must rely on drawing cards, matching cards, and on-the-spot operations to win in parallel. The protagonist was originally just a low-level sparring partner for the professional team's power-up deck, but because of a "kitchen waste card" that no one liked, he accidentally played an outrageous chain and was forced to replace the absent player. The league's giants treat cards as a capital game, but ordinary players use it as street smarts and on-the-spot tricks. The protagonist has to lead an Internet cafe team that is about to break up all the way to the professional qualifying tournament. The core conflict is: Can a group of ridiculed motley crew use the most unorthodox deck to overturn the version of the answer in the most formal league.
