I started from the bottom :P I didn't even know what a shiny was when I first started :P I found a few generous people and they've helped me clone ... So, bassically, I got my hands on somthing valuable, cloned, and kept trading. Bassically moving up the latter... Somthing like Shiny to Events to EV'd to IV'd, and from there, expand. Luckily, PC is pretty well developed and you'll be able to start out relatively in a high position. My advise is to get an AR. It saves a whole ton of time in cloning. Find somthing, clone it, distribute, and in the process you will get many other ones :P I sound like some kind of trade bandit from the mafia o.O It's not that bad
**In my opinion, preparing for every single breed seems like a pain to me, It's faster my way :P Smogon would be a step higher for more oportunities ;)
