Not to mention Control Winds is kinda like druidic Telekinesis...not a whole lot you can't solve with a tornado that moves with you.
You only get it after 1d6+5 hours though. Also, I can't seem to figure out what the advantage to knowing a domain spell is, since it specifically says "Divine Spells known or not take...". Any idea? The only thing I think spells known does for Sha'ir is make spells show up faster, and divine spells are slow.
Edit:
I found it, you specifically take a -6 penalty to get Divine Spells you don't know, so that's the advantage. So unless you want to waste a spell known on a spell it takes you d6+spell level hours to retrieve, from a limited list (which is posted in its entirety above) I think that's basically a red herring and it should be ignored. I originally thought once you just needed a random divine utility spell you would use it for that, but this list doesn't seem to help with that as I don't see much utility.
I need to look in to customize domain from Dragon Magazine next to see if that has a positive interaction with this class or not.
Double Edit:
Control Winds lasts long enough that it might be worth it. I will need to look in to other spells with long durations.
Triple Edit:
I'm going to start color coding the divine spells since they're so limited. Everything is starting red until I decide otherwise. The color coding is not necessarily for how good the spell is, but how good the spell is to retrieve as a divine spell. It's worth noting that the ability to retrieve divine spells allows us to qualify for Divine PrC's even with this limited list. Sha'ir/Dweomerkeeper might be a good decision though we would need a way to get the Magic domain. Also Dweomerkeeper specifies you need to convert prepared spells so we'd still need to call up SOMETHING in order to cast the spell. All in all I think that's probably just giving us redundancy with the mantle although the usual suspect of Supernatural spell still remains. Divine PrC's are something I should investigate as well. The list of things I should investigate is getting lengthy.
Current Points of Investigation:
Customize Domain
Domain Spells with usable durations
Divine PrC's
