I'm all up for a tie, for several reasons:
First, as has been mentioned, it's casual, and a 6-1 record is pretty darned impressive, no matter how we reached it.
Second, breaking ties should be decided before it started, as it will lead to unfair solutions (I believe that you definitely have a good matchup against me if we go to head to head, and that I have a better matchup than you versus the BPC storm deck)
Third, why fix something that isn't broken? I have done some research, and there is no official way to break these kinds of ties, so obviously the correct result of the tournament is a tie.
