After a few years in VGC, and seeing the huge interest in tiers like OU, UU, etc., I thought I may try one out in downtime when VGC isn't going on. I do understand a few things about tiers, but which one is best for a noob? Is it a good idea to jump straight to OU, or are lower tiers even easier like I've assumed? As you can tell, I don't know that much about this style of battling. Any help you can give me on this would be greatly appreciated.
