I traded some of my Battle Frontier Pokemon from Emerald to XD yesterday to use in the Orre Colosseum. I was on the Snattle round. On the first battle, I came close to losing because I had my Metagross use Explosion on the same turn my opponent used Protect. Fortunately, my Gengar's Petaya Berry activated and allowed me to KO the last Pokemon. Next two trainers weren't too bad, but the OHKO trainer's Dugtrio did get two Fissure hits in a row. Snattle was really easy, though. I lead with Gengar and a Protect-using Flygon, so his Pokemon's Explosions didn't do anything to me.
