Restarted LeafGreen yesterday when I dropped my GBASP and i lost my game...in Pewter City now, about to face Brock. Team is:
LV 15 Charmander, LV 14 Pidgey, LV 15 Butterfree, LV 14 Rattata, LV 15 Kakuna (...?) and LV 14 Pikachu. Yes, I know they are all weak to Rock attacks (except Rattata) but if you use Sand-Attack on Onix you can Metal Claw it out while it hurls boulders at the wrong places.
