After playing this game through nearly four times, the units I have used the most are these:
EARLY GAME
Royal Snakes
Griffins
MID GAME
Orc Shamans
Elven Archers
Hunters
Dryads
Demoness
Lake Fairies
Sprites
Horsemen
LATE GAME
Emerald Green Dragon
Red Dragon
Black Dragon
There are others, but I seem to come back to these over and over again.
