Total - 1745
I tend to use this list aggressively with the Annihilation Barges and Triarch Stalkers moving forward in pairs as fast as they can. In a perfect world, the Stalkers take out tanks and then their paired Barge fries the troops that get out. With no tanks then the Stalkers target infantry units so that the Immortals can gain twin-linked.
They also screen Zahndrekh and his unit of Immortals, letting him grab objectives.
The other two Immortal units are joined by Court Lords which come in from reserve in the Nightscythes. Again, these are pretty aggressive and will power forward 24" from the board edge- Immortals get out and move forward to set up a beach head for the advancing units. If possible these guys come in on a flank so that the 'Scythes can get another turn on the board at least before leaving the battlefield.
Generally a wall of AV13 is pretty scary and pretty difficult to get through- this lets me move my scoring units around behind the wall and grab objectives and offer supporting fire.
The sheer amount of shots this army can put out with all the tesla is pretty damn scary too!
