Throw stuff at a page and see what sticks....

So we have the statistics that a monster might have - Guile, Magic, Strength, and Swords (ability to inflict casualties).

Now we need some classic monsters/forces that might follow an overlord and roughly what stats they would have.  Feel free to chime in on the comments......  

Your bog standard unit is the Orc - so that is strength 1.
Then there is the Urak Hai who are an orc with more capacity for violence - so strength 1 - sword 1.
Then there is the Ogre who is stronger then the orc - strength 2.
Then there is the giant who is the strongest  - strength 4 (but vulnerable to guile in some way perhaps), sword 1.

Then we have the kobold- cunning but very little else - with guile of 1.
Spiders are creatures of guile and poison - so guile 2, strength 1, sword 1.
Assassins are devious and clever - guile 2, sword 2
Drow Knights are as tough as they smart - guile 3, strength 3

Evil Spirits seem to be your best simple magical creature - magic 1.
Ghosts are a step above them - magic 1, sword 1.  Something that will end up killing the stuff it faces.
Succubus are clever and magical but not that strong in a fight- guile 2, magic 2, strength 1
Ogre mages defy the stereotype of the weak mage - magic 3, strength 2.

Two other sets of things might turn up - things that can fly, things that can bash down castle walls - so that's key words 'fly' and key word 'siege' sorted that might turn up....

So
Battering Ram - strength 2 - keyword siege.
Black Swans - Strength 1 - sword 1 - key word flying

Dragons are the biggest and meanest creatures - since there strong, cunning, magically powerful, can fly and horribly dangerous.  So strength 3, guile 3, magic 3 and 2 swords - keyword fly.  That would mean a dragon would lose to a giant apart from it's vulnerability to guile however.

I suspect that's enough to throw different combinations together to see what comes out on top - is strength just best?  Does guile or magic make a big difference?  Is it just the biggest stake that wins?

But suggestions more then welcome......
