What early game units do you think scale well into the late game?

TItle. Just curious what units from the early game people keep using into the late game. For me, such as the Dwarfs, I rarely, if ever, remove Grudge Throwers from my armies simply because they are extremely effective for anti-infantry purposes since they also have AP damage while having better range than Flame Cannons or Organ Guns.

Of course you have other staples like Dark Elf Darkshards that spring to mind, plus the Dark and High Elves artillery pieces scale fairly well IMO since it's their only artillery.
