Great deck! Played against it - very good control and awesome combos to make lots of big flying tokens. Tough to beat!!

Mana Tithe would do that for you
you can also throw in Rebuff the Wicked to protect your enchantments, but only when they're on the table. Won't help against a counterspell.
I would slap in Greater Auramancy to give all your enchantments shroud since there are so many destroy enchantment cards. Great mana curve - really curious to see how it plays!
