Which unit in the Necropolis castle do you like the most in terms of appearance?

Yes, the banshees, even though they are pink, look better than the messengers because they have a skull instead of a face and scarier hands (like a skeleton). The princes didn't impress me much; I think the higher-tier ones are better. As for the dragons, I don't even know; one is black, the other is white, two funny geese :)
