Hi!

I was minding... How I can know who is the first team to play in round?

It's just coin flip for the first, then alternate? Thank you :)

first turn is random based on a randomised logic seed while every turn after alternates at least in 2 players.

I've been wondering about that too. I don't know, but it feels like i'm the last to play. Unless when i host, then i often start the round.

You can actually verify that by having a look at your saved replays.

First turn is random, but the players health bars are always displayed in turn-order (top to bottom - until damage is received by any player).
