Good late game SCs?

[Kuritza]

But poison golems have AWFUL stats. Afaik they are like simple golems, but they kill population and they dont have any magic... so with the exception of banefire shield which is maybe good vs chaff, they are even worse than an ordinary golem.
Who, in dominions 3, is a very, very bad SC.
Sea troll kings make surprisingly good SCs, when properly equipped. Quicken self, breath of winter (chill aura + cold immunity), regeneration, 60 hps, good MR, all in all a very good chassis. But they do need some reinvigoration, vine/eye shield and some low enc armor, rainbow or robe of shadows. Really, you should try it.
But thats more of a middle game choice - I thought we discuss top-notch SCs here.
