Rules: You cannot request for 4, 5, 7, 8, 10, 18 or 19 to fight as those teams only have 1 and automatically advance to finals. Try the ones with more characters like Team 3, 6, 8, 9 or 22. Villagers with their names colored are Nongfu Springers (农夫山泉).
You must request fights like this: "Team [number] fight" or "Team [number] vs [number] fight" or "pink/purple/blue-colored names OR blue/pink/purple nongfu springers fight" in the comments Characters will fight and fight until there is one of each left.
