I have had a think about this. I was trying to be impartial, but I think I actually let that affect me to be more lenient at first, or at least as lenient as I would have been at the start of the event, rather than with the precedent of illegal submissions so far.
Personally, I would not have made ANY of the illegal submissions 0 points. I would have allowed all to be voted on, with a 'half winning points' penalty.
However, ALL illegal submissions so far have received 0 points.
The 1000 word limit is described as a clear rule, and it was even mentioned in this round's Round page.
I think it would be very harsh on Paratus and Green Night to arbitrarily chose which rules stand and which don't. this rule was broken by 17%. Green Night's trio deck submission was broken by 3.3%.
