Well, an anarchic celestial axiomatic fiendish tiny air elemental has got a few nifty benefits like linked minds and a 100' fly speed, but honestly I don't have any way to give it decent firepower. All the template stacking would probably only be really worth +2 LA at most, since the templates are bad for their LA to begin with and they overlap heavily.
Share spells + persistant electricity substituted sculpted body of the sun will be fun once I get the combo set up, though. Turns out energy vortex is instantaneous (and not 1 round duration as I had though), so this is the next best thing to it. Energy resistance 10 and fast healing 5 make my familiar able to handle the raw power, and effectively gives me fast healing 3 or so. Which is a pretty good combo, but a little weak for level 12.
Embed component is helping my hp a lot, so I suppose I can't complain.
