A valid question!
Have your lists submitted two days ahead of time please. I can accept just about any format, but if you scribble it on paper and send me a scan, you will be dealing with one Angry Davis. If you don't have your list submitted ahead of time, you will not be eligible for competition in the competitive bracket.
You can bring your list in the day of if you wish. We do like seeing lists ahead of time just to make sure there's nothing blatantly wrong with them, so don't worry, early submission will NOT put you in the competitive bracket, but you make a Friendly Davis.
IN EITHER CASE:
Make sure you bring additional copies of your list ahead of time! Don't be like me at the twin's tournament and write it up the day of. You will be docked 1 Command Point if you don't have additional copies available for your opponents.
If your list is illegal due to incorrect detachments (too many units in a detachment or too few), we will correct by putting any units in the offending detachment into an Auxiliary detachment, which will cost you a ton of Command Points.
If your list is illegal due to incorrect points (unit costs more or less than it should), the offending unit will be removed from your army. This may result in an illegal list due to incorrect detachments, which will result in the above modifications.
If your list is illegal due to having a single-model unit above 31 power (32 power or higher), that unit will be remove from your army list. This may result in an illegal list due to incorrect detachments, which will result in the above modifications.
