I did mean Mesprit, and he is a pain in the butt. I got the other two, and though one was frustrating a bit, Mesprit is just driving me crazy. He's down to around 1HP, and I try using Quick Balls (apparently they have 5x catch chance on the first turn) but it's just no dice.

On another note... does anyone happen to have a Piplup they'd like to trade? Maybe a female one they can breed, or maybe even a Ditto they can breed it with? I've already got the two other starters, and I kinda want the third. And GTS people have crazy requests (no, I do not want to trade a level 100 Dialga for a level 1 Piplup)
