New Year's Duel Tournaments. Regulations, Rules.

In my opinion, the first option is the most acceptable, as usual, everything is standard and clear, a preliminary warm-up before the playoffs. I don't like the second option (no offense to Leo), as it requires playing too many games overall. That's a huge number, and I won't have enough time to play 5 duels with everyone. The third option is also not a great option, but if the first one doesn't appeal to anyone and isn't chosen, then we can consider this one, but it needs to be refined. Sincerely, Lord of Vampires.
