I see three rarity errors there, assuming that the colector's numbers are accurate:
-Zapdos should be holographic Rare, as it comes before regular-Rare Aerodactyl.
-Vaporeon should be Rare, as it comes before the Uncommon Ambipom.
Darkness Energy should be something above Common, considering Metal is classified as Uncommon.
That being said, why is there a Drifloon in this set and not Drifblim?
It doesn't matter how "bad" peple are claiming the set to me, since I'm into the Pokémon TCG more for the artwork than anything else. I haven't seen most of the artwork for this series, but from what I HAVE seen, they look marvelous.
