first blood is 40k..
Ethereals are a pain to a few armies but generally I would ignore them. The threat of daemons and the need to take a high level mage to try to up magic defence to keep them alive means few will run a strong unit of ethereals in small point games.
You might find a few random bases of spirit hosts which are still very annoying but they aren't a threat to your saurus blocks with their +3 static combat res... but might hold you up for a turn or 2.
If you do face a big unit of ethereals then you can limit the damage a little by hiding the priest in the saurus... but generally you'll lose. All armies have that sort of list that they probably aren't going to beat, its a risk you take and is unavoidable.
