Playing cards. Spades represent strength, hearts represent wisdom, clubs represent luck, and diamonds represent wealth. Starting from A, ending with K, from weakest to strongest. There seem to be two missing cards, two ghost cards, or Jokers. Is the Joker card strong or weak? No one seems to be able to define it accurately. Because Joker itself, although it is an "Extra card", has the rules of the game printed on it. A peaceful world does not require superpowers. It is destiny for mortals to follow the laws of nature and live, grow old, sick and die. If something unexpected happens, someone must be needed to fight against or protect something. Just like the hero versus the devil, the warrior versus the dragon. Participants in the Poker War are called gamblers, and gamblers fight to protect the plane from being invaded. However, most gamblers are not that noble, but they are also motivated by profit, hunting down invaders in exchange for strength, wisdom, luck, and wealth. There is no just side in this war, only positions and desires. An independent plane, similar to our real world. Modern life with a slightly higher level of technology.
