Heavy Support:

Ravager w/ 1 disintegrator. 110

Setup:

Advance:

This is an easy setup.
put three warriors squads on each flank, with a ravager behind, and then add three wych squads to one side. Put your two lords on the same flank with the wyches.

This is a good tactic, it will force your enemy to commit heavily to this massive assualt force, and you have a force large enough to hold them back on the second side.

When advancing, go quickly on the larger flank. Move your second flank, but only 6" at a time, so you slowly gain ground on the enemy.

Leaving the second flank moving slowly will keep his defenses resting before they get to you, and so they will be useless, because he cant move them (otherwise just wrap around him) and he can get them involved because your too far away.
That is the best way that i can think of to use this list.
