This is the force I took out on Saturday. I faced Brettonians (Commander, 2 Heroes, 2 Damsels, 2 Grail Knights, 6 Knights, 3 Squires, 4 Men at Arms and 4 archers plus some magic items including a dispel scroll thing).
I took the following:
Tomb King
Liche Priest on Zombie dragon with sword of might
4 Liche Priests
4 Skeleton Warriors
4 Skeleton Archers
3 Chariots (1 with sword of fate)
2 Skeleton cavalry
2 Carrion
Bone Giant
Sphinx
Skullchukka
Bonethrower
2000 point total
This was based on what I had.
I won the game, as I lured one brigade of knights forward with my cavalry. My opponent unwisely committed his general, and while I lost five stands of cavalry, a unit of skeleton warriors and 2 stands of archers, I then swarmed the brigade with 6 units of infantry, the bone giant and the zombie dragon, and killed 3 units of knight, a unit of grail knights and the general, breaking the enemy army and winning the game. The carrion hit the 2nd knight brigade in the side and killed 2 stands for the loss of one, disrupting the 2nd knight brigade.
My opponent made a number of mistakes, both in deployment (he had the knights brigades on one flank, one behind the other, preventing them hitting in the same turn) and in employment of his forces (his expendable infantry and squires did very little, and he committed his general to combat, allowing him to be killed).
However my chariots did pretty much nothing, and my warmachines killed one stand of squires before getting overrun.
My liche Priests performed very well, the highlight being one killing a stand of grail knights with death touch, which left the general only accompanying one stand.
How should I improve my army? I've got a feeling a full brigade of cavalry (240 points) instead of two units might be one thing to do, ditching the warmachines. Should I ditch the chariots in favour of 8 more units of warriors and anoth liche priest?
I did sit down with my opponent and advise him never to commit his general to combat, and to get a hero on pegasus with sword of might for tipping the balance in vital combats for next time.
