Awesome!! I has my six pokemon now. I'll start the challenge once I finish my sapphire speed run.
SAPPHIRE SPEED RUN UPDATE
I can't remember much because I did it about 8 hours ago, but I'll do my best to remember.
I got to the third gym after a long time. Can't remember why it took me so long, but it did take me ages. Beat him without much trouble 'cause he was an electric type leader. He didn't do too well against my Marshtomp's mud shot (no-one did really). Beat him at 1:41.
The next gym was a bit faster, but not by much. I had a few unnecessary battles on the way to stop team aqua from doing their evil stuff, but I eventually did it and went to battle Flannery, the fire type gym leader. I figured this would be an easy battle seeing as any of my STAB moves would be super effective. I OHKOed the two Slugma and thought this was going really well. Then her Torkoal came out. And then, guess what happened!
I 2HKO it and get my 4th badge at 2:21.
I was right about this being an easy battle. As well as that, Marshtomp evolved!
