I switched-up the list a bit and played another 1,850 list against a formidable Eldar commander. Random Mission from the Battle Book, Page 78 Fighting Withdrawal - The Eldar took the place of the Tau.
225 StormLord
140 4x Necron Lord
40 4x Warscythe
170 10x Immortals
170 10x Immortals
130 10x Warriors
130 10x Warriors
120 8x Scarabs
120 8x Scarabs
105 7x Scarabs
200 Monolith
150 3x Tomb Spyders
150 3x Tomb Spyders
I spread the Necron Lords out to the Troop squads (buried a Str 7 Power Weapon in each unit)
Lined the Tomb Spyders up behind the 2-8x Scarab units, the 7x Scarabs were used to go after his Eldar Sniper unit.
The StormLord kept Nightfight up for 3 turns. Lightning Strikes killed one of his nasty pie-plate shooting vehicles and his CC unit transport on turn 1. Lightning killed the other pie-plate vehicle on turn 2.
The 2 8x Scarab Swarms were bumped to 11 bases each on turn 1 before they took off across the field.
All 6 Tomb Spyders ran to keep in range of a single trailing Scarab (lagging behind on purpose) - allowing them to bump the unit up to 17 Scarabs the next turn before they piled into close combat!
With Nightfight the Eldar only got off 1 vehicle and 3 troop units worth of shooting the whole game.
We forgot about the Monolith and it sat beside the table turn 1 - I rememebered and deep-struck it on turn 2 (a very rare direct hit).
I pulled 1 unit of Warriors forward for rapid fire mayhem just before the largest blob of Scrabs charged-into Close combat
A unit of Scrabs ate a vehicle on turn 2 (even after the vehicle moved 12" the Scarabs still reduced it's armour by 6 before wrecking it) and headed towards tasty Eldar troops (yes, they taste like chicken).
The Eldar commander tossed in the towel at the end of turn 3. He had 0 of 4 vehicles left, 7 basic troops and 1 HQ model - everything else was wiped-out.
Necron losses: 4 Warriors, 1 Immortal, cumulative 6 Scarabs (I created 18 new Scarab bases).
This is my 5th battle using the new Necrons - In all games the opponent has conceded by turn 3 - only 1 went past and that was just to see if the new Necrons could table Sicarious and the Ultramarines (they did).
Codex's beaten so far:
Grey Knights (4 vehicles, no LOS required shooting-heavy)
Blood Angels (10 vehicles - Tournament spam)
Imperial Guard (Troop & Troops & Troops + LOTS of Autocannons)
Ultramarines (Balanced Tournament List)
Eldar (Nasty-nasty psyker - Tournament Balanced list)
This seems to be the most effective "basic" list I've used so far - No new, expensive GW vehicle models required. The Necron Lords could possibly be dropped to add Orikan to the list to hamper enemy turn 1 movement.
The opponent is so focused on handling wall-to-wall Scrabs in nightfight that by the time they begin to come-up for air the unmolested Warriors/Immortals and Monolith(s) are upon them.
