Earth: Troll kings court is great, mechanical men are useful, siege golems are tough, fairly hard hitting and destroy castles easily, iron dragons are also very tough but they also fly and have good resistances. Crushers can be extremely useful if you get them early because they are fairly difficult to take down without magic.

Water: Sea kings court is good. The Sea king himself is useful and the regenerating sea trolls(who tend to bleed alot)+the shark summoning spell can dominate underwater.
Kydnides are nice too.

Nature: Lamias are great. Vinemen and ogres are also nice - particularly when you get a boost to summoning.

Astral: Ether warriors are nice. Not much else.

Death: Ghosts are great, chaff, particularly dispossesed spirits are great, wights from the legion of wights spell are good and troop tartarians are fairly good.

Blood: Imps can be a pain but arent too powerful. Devils are always nice. Storm demons/frost fiends/fiends of darkness all have their uses, particularly the fiends of darkness due to stealth(give a stealthy commander rod of the leper king). My personal favourite here would have to be demon knights - they are absolutely awesome with their great stats, abilities and equipment.
