My intuition's not good for this. White does get 2W 2/2 flying with upside, and creatures do get "C, sac: destroy target artifact or enchantment" as upside, but I agree you'd probably normally be happy to play as many as you can get in white, which is perhaps a bit harsh on artifacts and enchantments in a set with many artifacts. But then, white clearly does get good answers. My intuition says it's at the top of the curve, and printable, but probably better if not quite as all-upside.
OK, following the example of Goblin Replica, activated abilities that can destroy artifacts in this set should cost more, particularly at common. So I've bumped up the cost. Now if you're using this as Disenchant you're paying , which is a lot to pay in anyone's book; and if you're wanting to keep it open for a response, you're having to leave up. I feel better about it now.
The playtesting will likely include a pilots deck vs a connectors deck, so if this seems too good in that setting, I'll consider upping the cost even further, or making this uncommon.
On the one hand, this is just a minor tweak on Wild Griffin or Ronom Unicorn. On the other hand, this would go straight into several casual decks I have as an evasive maindeckable Disenchant. Is it too good? Compare with Cloudchaser Eagle and Kor Sanctifiers.
