Ok after playing 30 battles, I have to say I like the metagame.
It started pretty bad for me with the first 5 games being decided before the players did a thing (Archeops vs 6 slower mons weak to one of its stabs or Zapdos vs team full of grass and flying types) but now it's much better. The metagame is very offensive, and if you're lucky enough to have Stealth Rock, you have a huge advantage. Poor defensive mons like Blissey and Skarmory can't really do a thing when there is such a great pressure.
The best mons so far are mixed Tornadus, Archeops, Zapdos, Staraptor, Articuno, and Aerodactyl. They are just so strong it's not even funny. The odd Sigilyph with the right moves is beastly too.
Also, I've successfully spun Rocks and TSpikes with Delibird at least twice and that alone is funny enough xD
