Previously, I used this setup against the Haven faction – the advantages are the inability to cast mass Plague, and controlling melee units is not as effective, and the Banshee's special ability is not that strong. Of course, there are also disadvantages – Angels are quite easy to kill, and Vampires can destroy half the army.
Hagish-Orson: there's a mistake in the positioning of Hagish and Orson; it works against beginners. In general, a skilled Orson places skeletons near the liches and teleports spirits to the Cyclops – they are killed immediately, along with the Trappers and Shamans, and the game usually ends there.
