One more spot open, not sure who will fit in it yet!
How did you get those sprites in your post? I know it's a little unrelated, I was just curious.
On topic though, I recently started a new game on my Platinum version, and my team are as follows:
Level 9 Chimchar - Scratch, Leer, Ember, Taunt
Level 7 Starly - Tackle, Growl, Quick Attack
Level 7 Geodude - Tackle, Defense Curl
Plan on hitting up the Oreburgh gym. Hopefully pull through there. Yikes.
