Personally, I like the idea of having a random group stage and a bracket-style playoff, but I'm also open to other options. The main thing is that in the group stage, you need to play many games, and the bracket system takes a significant amount of time. Of course, with a random system, completely unplayable pairings can occur, such as an Elf Mage, in which it is simply impossible to win, but that's why the random system should only be in the group stage, where losses in such pairings won't be so critical.
