Best sacred units?

[Oversway]

I have a hard time doing anything with the c'tis sacred serpents (not counting DT). They are pretty expensive and die fairly easily. I don't often play c'tis with a bless effect so maybe they are more effective than I realize.

I havn't bothered with ermor Wailing Ladies or Knight of the Unholy Sepulchre. The ladies don't seem worth 15 death gems and I never seem to get enough knights.
