Hello @Fluitzzerg , I don’t speak French but I can answer you in English if it is useful to you!
How great that this is your fourth tournament and that you want to do it in duos, it’s a very good idea. yeah, you can do what you’re thinking but you’re going to need to look for different devices and set them up correctly.
Class selector
This device is used to choose the team for the players.
Player counter
This device is used to show the number of players on each team. It helps show other players how many people are on each team.
Player Spawner
You must also use a player spawner in order to spawn the player in the selected team.
And finally you must change these options in island settings (Teams and Team Size)
With these devices and that island configuration you should be able to make it work. I’m attaching the documentation so you can check how they work and also giving you a small explanation of how you should be able to use them to set up your team tournament.
Hope this helps you build your new duos tournament!!!
