Creating a team

I created a team because I'm interested in balanced tournaments. Meaning - no berserk, no extra points for consecutive wins, etc.
What I'm unsure about is how do I get people to join?
Do I publish it somewhere?

Well, concerning your team here on lichess, people will rush to tell (an report) you as soon as you start posting its name and link in the forums, the private message inbox or the tournament-chats - so that isn't an option. However, you can "advertize" in your profile description, your blogs and - if there is interest - you can talk to other members.
But how about another approach? Why do you want to get members - what are you offering, is it special? Is it unique or does another, already existing and larger, team exist, which does the job better than your team? Do you intend to have something of a private-club, for the people you already know, or is it open for everyone to join? Is your team actively participating, does it have a community, etc.? These questions might help you to shape the team.
A quick look at the team-description and it seem like it is the perfect team for people who want to play, as you already mentioned, the "basic" arena. So in that sense it is unique - but I am sure you will have fun growing a community in the online-space that is lichess.

My personal opinion is that the whole reason chess is so good is because it's balanced. Meaning, my Knight is equal to yours. There's no special gear or "luck" that offers anyone an advantage. If someone wins it's because he's better and not because he has better shoes or a more aerodynamic helmet.
More so, once you introduce imbalances to the very game it essentially stops being chess and becomes a variant of chess.
With this in mind, I sought to create tournaments without berserk and without extra points for consecutive wins. If I could, I'd remove tie-breaks altogether and have the group fight it off until a winner emerges.
As a side note I'll add that I obviously find competitions ending in an armageddon where one side has more time but has to win and the other will "win" by drawing to be utterly ridiculous and not chess at all.
