Trying a Randomized Hardcore Nuzlocke with Every Pokemon: Charmander Edition

I am trying a randomized hardcore nuzlocke with every pokemon. This one is with Charmander in Heart Gold. No catching other pokemon (except for HMs) and no using items in battle. I tried to adhere to the level cap but so many trainers that I couldn't avoid had legendary or fully evolved pokemon so I was unable to avoid all the experience. I did not think this was enough to discount the run. I avoided as much wild and trainer pokemon as I could (once I realized I was having a level issue).
