Which units would you replace in the Sylvan castle?

Why criticize Ents so much? They are cool guys, and without them, Sylvan wouldn't be Sylvan. And the dragons are beautiful... big... the fastest creature at level 7. And in general, it would be good to replace Dryads, for example, with... beautiful, strong elves (something like Furies, naturally with the parameters of the first type). For example, their ability could be: the more elves there are, the higher the morale of the Dancers and Archers).
