IMO ghosts are an excellent troop summon. The spell summons extra ghosts if you have high magic levels. IIRC a death 7 summoner will get 7 ghosts per casting. Death is quite easy to boost with items so it's quick and cheap to gather a powerful army.

Ghosts have a chill aura so don't use them with regular troops. They are frightening, ethereal, drain life and can enter the sea as well as having good stats across the board except for prot - and their etherealness makes up for that in sp at least. Also, unlike wights they don't suffer from exceptionally low battlefield movement. Against the AI they should be overwhelmingly powerful.
