I've started a new game on my Soul Silver as i want to catch all the Pokemon available then trade them to my White 2.
My team so far is:
Zoomzoom - Togepi - Lv8 - Naive
SauraFlora - Chicorita - Lv11 - Serious
Ampaa - Mareep - Lv13 - Hasty
Staypuff - Docile - Lv11 - Docile
When have just beaten Falkner and are now catching all of the Pokemon in the area who we haven't caught yet.
