Which units (in terms of appearance) do you like the most in the Elven Castle?

Imagine a bloodied unicorn with fiery eyes. Its horn is sharpened into a blade, and its hooves have spikes. It's wearing armor that's been scratched by a hundred swords... Let it be a fantastical creature.

I imagined it, it's creepy, but still, you have to agree that unicorns are a weak link in the Sylvan army in terms of appearance; they seem a bit underdeveloped, especially the ones that are supposed to be sacred.
