Good tournaments system. pls

Best tournaments system which i saw, was in game Artifact. Any people can made any tourney (relegation or swiss) and spectate it. Drawing, tourney points, places - system calculating automatically! Every day you could find about 10 tourneys for play. After 2 months Artifact died, but this another story.

Now in TFT you cant easily create tourney. Some streamers start play with gamers and lose game for observer mode.

I am sure that there are many people which want to play in tournaments. And many people ready to organize tournaments. Please create good tourney system. Only 2 clicks and tourney created!
