Which units would you replace in the Sylvan castle?

To be more precise, the dark-haired elves were from the Schism faction, while the light-haired ones were from the Sylvan faction. As for Lorien, I don't remember. They seem to have been albinos. Archers are masters of the bow, and dancers are all male. The only women in the elven army are the dragons – the earthly embodiment of Silanna.
