The Battle Institute test in San Diego was fun. I got a 6460 (using not-Unova-exclusive-Pokemon though, while the opponents were all Unova Pokemon). I don't remember all the battles but the opponents seemed to get progressively better; I never did the non-downloaded one so I don't know how to compare it.
441 D/Cs and counting, baby!
