First of all, your skills must be high. If at least 43 classes form a team, you are also involved. It would be better if the weight is not light. Let the class serve you.
Then, I play football with my friends in class every day. First, find someone who has a good relationship with your class. Don't try to eat a big fat man in one breath. First, organize a small-scale game. If you think so, others will organize a game. As long as you can lead four or five classes and then discuss with the captains of other classes, basically anything can be done. One premise is the first one, you should have weight.
The third is the competition system. You have 43 classes and many more. No matter how many, we must play the knockout first, because there are too many words in the group match of Class 43. There are only 32 teams in the World Cup, right? First, eliminate half, leaving 22, then eliminate half, leaving 1 1. At this time, the rest are basically powerful classes. The remaining 10 teams will continue to be eliminated, leaving 6 teams. At this time, no matter whether it is eliminated or recycled, there will basically be top players left. However, recycling is not recommended. In the case of imperfect system, water often appears, which is very bad. So if all 43 teams participate in the competition, they will all be eliminated, or a double-cycle elimination system can be adopted, just like the elimination stage of the European Champions Cup.
