This is a great post and I will be looking forward to more of these, mainly to make sure I keep up to date with the metagame.
As for what I have seen, I generally agree with what you put but I have seen decent amounts of P-Z, Hippodon and of course Weavile too. A surprisingly little amount of Celebi and Heracross however. Jirachi is very popular (virtually all with the new physical set), with good showing from Swampert and Rhyperior (obvious reasons). Lucario isn't as popular as I imagined either.
