@Morzone, I'm pretty sure this is how it works:
There's the Qualifying Rounds, and the Final Round. You qualify for the Final Round just by going to the Qualifying Rounds and surviving. I think it was mentioned you could simply dig, fly, teleport, whatever to get out of the arena in the qualifying rounds.
I'm pretty sure that if you do that in the Final Round, then you're OUT. And whoever the last team left with Pokemon alive is the victor.
...Or I Laura got wrong information and was just kicked out of the Bloodpit Arena.
