Hmm...interesting. Originally, I was going to have a Challenge Match be displayed as coming up, and then you can decide who to stick in there (presumably your best warrior), but there would be a stat penalty if you lose, so it might make sense not to use your best warrior at times (you don't want your best warrior to get his stats dinged, as that could mess up your season).
But you may get a stat or money bonus if you win, which in turn may urge you to use your better warrior. Decisions, decisions...
