Which units would you replace in the Sylvan castle?

Don't touch the Druids, they're sacred! And no one is suggesting making Pegasus a second-tier unit. I just want Pegasus, they're beautiful. And besides the Dancers, there's no one else to remove, so by elimination, that's what I came up with. By the way, Druids pack a serious punch. And their magic could be buffed. And Unicorns are too weak. I think they should be a higher-tier unit, definitely!
