Don't forget that while Bandar Log is chasing the research for Ghandarvas, they also get access to Akashic Record. I use it only for Mountain/Forests and other high frequency provinces and have not been disappointed, despite the fact that you have other things to spend Astral on.

I also favor the Nature bless and like Wooden Warriors for BL, so the Mother Oak is almost always mine. That seems to keep a steady supply of summonable mages.
