Try using Lorien Then... of course you aint getting something as kin to Thranduil in Lothlorien lists but....can prove fruitfull in a way if you get some Galadhrim knights maybe...
Keep in mind youre using mirk cav, mirk cav aint that much special other than a light armoured guy with fight 5, C5 and elven blades that get a banner effect around Thranduil.
Alternative to that mirk cav and perhaps a strong combination although you lose numbers would be elrond´s sons armoured and mounted with bow.... they cna offer a nasty punch and plenty of might points.
Not much of an army but...
Elrond with heavy armour and horse
11 Knights of Rivendell with shield
Elladan and Elrohir with heavy armour, horse and bow
2 wood elves with throwing daggers
Lindir with heavy armour and horse
total: 700
