There was an issue a while ago when you share your decks online. Users report they getting an error message every time they do this. We are pleased to inform you that this issue has already been resolved. You can now share your decks online.
On a different note, prices for Aether Revolt on TCGPlayer are now available on some cards. The rest will follow tomorrow. If you can't see the price on a particular card, don't worry, we'll have it posted tomorrow.
Happy Brewing!!! :)
