Want to play a 2v2 match?

I'm probably one of the few who participated in a similar tournament and know how difficult it is to find a common time, a common version, establish a connection, and then adjust the rules to suit everyone.
1v1 matches should be discarded immediately. They are unnecessary and will sink the tournament, which will likely sink on its own. And it's better to form teams based on having common free time, a stable connection, and simply good relationships, rather than based on some kind of rating.

I have experience participating in a 2v2 tournament for Civilization III (also a turn-based strategy game). Very similar problems.
Of course, it's better to play in a team with a friend. It's about communication via Skype, joint decisions, different interactions, tricks, and the need for mutual understanding.
Connection is important; you can't play with a too slow internet connection or with frequent disconnections.
Time is a big factor; it's difficult to find 5 hours for four people to play simultaneously, and it's almost impossible to finish a postponed game. Therefore, it is necessary to allow substitutions of the main team without prior registration.
It would be very helpful to have simultaneous play during the first week.
The organizer should be given the right to prohibit the creation of a pair of masters, as a team that is too strong will kill the intrigue.
In general, playing in a team is about communication and a lot of positive emotions!
