I know you say you hate the pitiful HP Flying on Keldeo, but Icy Wind is even weaker. AND less accurate. If you can explain why you have that there, I'll listen, but I'd personally say change it. Icy Wind is pretty bad in singles.
Also, Air Balloon on Aegislash is pretty situational, and in my opinion, just not that good in general. I'd go for leftovers personally, or even weakness policy. In defense mode he can take an earthquake pretty well if invested in defense, and hit back harder than he ever could if invested in attack. Just a thought. Also, is pursuit trapping the Lati twins really necessary? You don't really have a glaring Latios weakness with ScarfChomp and Ice Beam on Deo-S both. If I were you, I'd replace pursuit with either Swords Dance or Substitute. But you'd have to adjust the EVs to accomodate for the different sets.
