Ok I have decided on the final list for my tournament worthy list, here it is

HQ
Lord, res orb, veil of darkness - 200
Lord, res orb, destroyer body, warscythe - 180

Troops
10 warriors - 180
10 warriors - 180
10 warriors - 180

Elites
10 immortals - 280

Fast Attack
4 destroyers - 200
4 destroyers - 200
4 destroyers - 200

Heavy Support
Heavy destroyer - 65
Heavy destroyer - 65
Heavy destroyer - 65

Total 1995

So all the destroyers including destroyer lord take a flank and cause utter devastation and hopefully split up the enemy army. The remaining infantry advance in a block towards the enemy, the lord joining the immortals. If any one of the infantry units (warriors or immortals) are assaulted the lord will use his veil of darkness to teleport them out of there just behind the other squads, opening the assaulting unit up to four squads worth of shooting in my shooting phase

Well that's it, any advice is greatly appreciated
