This is too pricey for what it does. enchantments can be countered by a simple Naturalize. I don't need anything else!

Run with Replenish.

Play with Enchanted Evening.

What a strange reprint. Are there any other "off-color" activation costs in Fifth Edition?
Stranger still that it later received a functional reprint, Teferi's Care.

@Nammertime don't think it would work that well with Enchanted Evening. Enchanted Evening makes permanents enchantments, it doesn't affect spells. So if someone used a artifact or creature, it only becomes an enchantment when it resolves and by then it is too late to counter. (Same principle as the ruling for Emrakul Aeons Born in relation to Journey to Nowhere.) So only the Arenson's Aura's first ability would be of use against them.

There's alot of enchantment hosers in magic, especially early magic.

I like the Enchanted Evening combo:

{W}, Sacrifice a permanent: Destroy target permanent.

That seems crazy good to me! Play it in a creature token deck for ultimate removal.

Yo dawg, I heard you hated enchantments, so we made an enchantment that lets you sac an enchantment to destroy an enchanted enchantment.

Naturalize doesn't counter anything, it destroys a target enchantment or artifact.

I managed to get this out one EDH game with Enchanted Evening, sacked my lands and wiped my opponent's board before dropping Opalescence and an Ancestral Mask on the aura, and proceeded to beat face with a 15/15 outdated sideboard card from 1995. It was a very satisfying moment.
