To be honest, I wasn't sure. I haven't checked the waiting battles yet. I only took Kam and Patar's battle because I'd happened to see them both active and recognized the names on the list. Oh, and cause the arena was fairly simple... I tend to be a bit absentminded so complicated arenas might cause me to forget to check for one of the arena's effects or something Why, you have one you'd like me to do? :P
