I'm just gonna say that I'm trying your challenge, and I have yet to upload the video, but the first gym is UNGODLY HARD if you chose Snivy and if you try it following all of the rules.
Question: How do you regard pickup? When battling with Pickup(for example: Zigzagoon), the pokemon will pick up the berries that the opponent uses. Does this count as a healing item/hold item? I don't think it does, but I just want to make sure, since that would make the points I got in that battle go from 55 to 50 ._.'
Another Question: Breeding. Did you take it out, or can you normally not breed after you get access to the route?
