HI THERE Saw you in the pop-punk thread, glad to see you're also a lover All Time Low rock, my mates are going seeing them next year, but sadly I couldn't go :-( BTW, I saw your hair in the picture thread, it rocks.
So you want me to restart Pokemon Emerald, try and fail to win the Battle Frontier, and instead of just keeping my Pokemon there for further training, you want me to just import them and waste all that effort on BF?
Honestly, I would have never gotten Regigigas if it hadn't been for cloning.
You have 72 hours. You must start Emerald, get a Totodile with perfect IVs and an Adamant nature, fully EV train it in Attack and Speed, raise it to Lv. 100, beat a facility in Emerald BF, import it to Platinum, and beat a facility there in that time.
