If your weak rainbow pretender is out alone when decent assassination spells can start flying, you can have few complaints if it gets killed.

I don't like acashic record for the most part because of the gem cost. Astral gems are incredibly useful, and I'm uncomfortable spending 25 that could be going to so many useful other ends, but I guess if you've got a wasteland or other likely province apparently gemless, go for it.
