Hmmm... I dont see what the structure of this list is going to do for you, I mean, standard Destroyers? Really? you could be spending those 80 points a bit more wisely
IMO.
I ran a 1000 point list for the 25th anniversary today and it faired me well, I used:
Overlord
Warscythe,
CCB
Overlord
Warscythe
HoD
Solar Pulse
HoD
Solar pulse
10 Immortals (Tesla)
10 Immortals (Tesla)
6 Scarab bases
Annihilation Barge (Gauss)
Annihilation Barge (Gauss)
5 Deathmarks
Small but organised and structured, with inter-changeable units, lots of firepower, anti tank and infantry plus it gives you a lot of strength 5 and higher shooting, with so many saves to make, your opponent will eventually break and his army should slowly but surely wither down (Depending on opponent of course)
Hope that helps at all!
