An attempt to organize a team tournament between countries!

in the case of 12 teams, I suggest 2 groups of 6 teams each, followed by a) the top 2 teams go to the winners bracket, and the next 2 go to the losers bracket; b) 1st vs. 4th, and 2nd vs. 3rd in a single or double elimination bracket. In such groups, there will either be no easy matches or only one in the last round for one of the teams, and each team will play at least 5 matches.
