Well i had some real though over the list.... I was even thinking in adding Sauron the Dark Lord (but that would be cheese), Shade or Gulavhar.... but at the end I decided something with numbers and something that could fight and cast magic as well...
Barad Dur
-Kardush the Fire caller-60pts
(don forget that he has fury, and can cast magical power with strength of 6)
-Orc Drummer-40pts
35xOrcs-210pts (with spears, shields, bows, 2hwp.)
15xMorannon orcs w/shields-120pts
15xMorannon orcs w /spear & shield-135pts
Dol Guldur
Spider Queen-75pts
NazgyL
The Dark Marshal on Armored horse-135pts
So this army is fast moving and has a lot of numbers... It´s only weakness is the lack of might points, but it has fury, and a Nazgyl with Banner rule to bulck up the force.
Total:69
50%:35
Bow:till 6
Might:5
so any more thoughts???
