School's League army list challenge!

[Mr Mystery]

So, inspired by our young friend's school league army building, I'd like to see what we can come up with ourselves.

Rules are simple. 600 point armies, with the usual minimums of 1 HQ and 2 Troops.

For me? Has to be my Necrons.

Overlord - 130
Warscythe, mind shackle scarabs, Sempiternal weave

Cryptek - Harbinger of Storm 25

Cryptek - Harbinger of Storm 25

5 Immortals - 85
Gauss Blasters

5 Immortals - 85
Tesla Carbines

5 Immortals - 85
Tesla Carbines

2 Tomb Blades - 70
Particle Beamers, Nebuloscopes

Annihilation Barge - 90

For me, covers most bases. Whilst I remain typically exposed to a determined charge, the army should continue to function after the loss of a couple of units. Vehicles are dealt with by the Crypteks, though given the low points I wouldn't expect to meet many on the field. Overall tactics remain the same as my usual ones, namely use the Tomb Blades to dissuade my opponent from bunching up (S6 templates hurt!) and otherwise mark a couple of units a turn and hammer them into the dirt.

Whilst it's tempting to drop the Nebulscopes and Annihilation Barge in favour of a Nighyscythe, in such a small game I'm not willing to risk unfavourable reserve rolls.

Overlord of course does what an Overlord does, and will sit with the Gauss Immortals for extra protection.

Legion38
recon unit
HQ
Master of the forge:100 pts


Elites
Dreadnought with two twin linked auto cannons:125 pts


Troops
5 man scout squad with sniper rifles ans heavy Bolter:85 pts
10 man squad of space marines:200pts,with plasma gun and cannon with a stormbolter for the Sgt.


Heavy
Thunder fire cannon:100 pts.

This is my all rounder list for quick games. I like it because it gives me some reach in the first round.

The necron list is great, as is the marine list. Wish my lists where like that.

The space marine list is 10 points over

[Pendragon38]

I'll drop the storm bolter that should work better

For my new Necron army I will probably get another battleforce (As all my other Crons are broken) and then mess around with the lists that Mr Mystery used, using more warriors then immortals (gotta love them 10 man warrior squads). But the annihlation barge is an immense vehichle, so one of them will help.
But I'm still not sure on an army, wether Crons or something else...
