As an option, I can write a few lines; it might seem a bit simplistic:rolleyes: We divide everything into stages.

Round 1 - random draw.
Round 2 and all subsequent rounds - pairs are formed based on the same number of points scored; repeated pairs are not allowed (in this case, the player(s) with the fewest points participate/are drawn).

- this is a perfectly normal option. Games are always between Might and Magic. Stage 1 - qualifying round. Based on the number of players, we conduct several rounds to eliminate players; for example, with 12-17 players (although I'm not sure if there will be that many), 4-5 rounds are sufficient. In each group, the top 8 players advance to the next stage. Stage 2. Several rounds(?). Again, round 1 of stage 2 is a random draw, and then based on the points scored. Games are between Might and Magic. The 4 strongest players in each group advance to the next stage. Stage 3. Several rounds(?). Everything is the same, with a draw. Games are Might and Magic. Stage 4. Final. Based on the points scored in stage 3, a match for 1st place is held between the players who took 1st place in their respective groups. The match is played to 2 wins. It is clear that in the final, there will be a battle between Might and Magic, and not, for example, Magic vs. Magic. The numbers and the number of rounds are approximate, but even so, on average, there will be 10-20 rounds with a final. And, of course, the more participants, the more rounds there will be. Faction restriction - it is definitely necessary to limit the number of games played with each faction to no more than 3 (+/-?) starting from the qualifying round and ending with the final. That is, there will be a choice: to save your favorite race for later and advance to the final with races that are less comfortable for the player, or to play with it immediately, but without the possibility of playing with it in the final.
