Which units would you replace in the Sylvan castle?

By the way, I was just thinking that we need to change the Druids. At the beginning, they are good because of their lightning attack, especially in several stacks, but later on, they only annoy me, as the damage from lightning is no longer as significant (due to the size of the armies), and their archers are completely useless. At this level, we need to put either really strong archers (by the way, I liked the idea of "forest beholders")), or something like the Pegasi from Heroes of Might and Magic III, naturally strengthening them (because in Heroes of Might and Magic III, I think they are too weak).
