pretty much all the rules on goyugioh applies here for tournaments as well only with these exceptions
1. xyz's and synchros are allowed
2. you have 3 days to duel, if you don't, then you report you waited three days, if you don't, both you and you're opponent are disqualified
3. no trolling during the tournament, you cant procrastinate the duel if you're about to lose, or stuff like that; or you are banned from a certain amount of future events
4.ill try to watch each duel, if i catch you cheating (looking in your deck when you not suppose to, intentionally drawing cards when you cant, et.) you are suspended from future events
5. no flaming competitors especially teammates during team events (you know what team I'm talking about) and anybody during single events
