Mine seems to be fine. If anything, the new fairy typing makes it much more difficult to kill IMO. At least until everyone picks up on it. Still gotta watch out for anything that might throw Stone Edge at it, though. That hurts. A lot.
I find roost on Togekiss much more useful than aura sphere or dazzling gleam due to its tankiness + leftover being the item of choice. You should also consider king's rock instead if you're not using roost or wish.
