I am stuck at 27 as well and this is my third tournament with the same round being stuck forever. It's not fun and I am going to stop doing tournaments for a while. Maybe this ridiculousness will be fixed at some point. I have been playing this game for a long time, and still like all my dragons, but I think it is time for me to go back to the basic game here.
Finished this tourney but I had to Ultimate Glasswing.
I used up all my data for this month on this tournament. Oops.
