If you run a tournament then it is you who make the games

If you wish participants to make the games then I'm not sure it goes under tournaments (I'm sure a Tournament Director will answer more specifically).
Also, if you do decide to run it as a tournament then IMO you've picked the most awful settings. Freestyle and Unlimited is a terrible choice because there's at least 95% that the player joining second will win. If I could suggest then best settings for 1v1 is Chained/Adjacent (Chained is more common) and No Cards/Escalating (though Flat Rate is also very common then I don't think it is a smart card choice).
If you make any changes then don't hesitate to let me know.
Otherwise good luck with your tourney!
