Is it open to premiums only or freemiums also? You should mention in it in the first post (if all games are played at once or one/two/etc at a time).
Also, I'm sure that you have reasons why you have picked the most slow settings (no cards and adj) but I would suggest you to pick something faster because games will take a long time to end and you might get really bored when tournament takes too long to finish (I made a mistake and used no cards games and had to wait for months and months games to end and it was really annoying).
Or if you wish to continue with these settings then maybe set some number of rounds and when the game reaches it then you will decide the winner some other way (who has most troops/territories/etc) so you would have some control over the tournament.
Oh, and I'm still considering participation, I'm not a huge fan of no cards, too slow for my character

Good luck!
