This is just a fun list i made using the 3rd ed cron book let me know what you think
HQ
Lord (Core unit of any Necron army)
Warscythe
Res Orb
Phase Shifter
The Deciever (Similar statline to Nightbringer but with fun utility)
TROOPS
14 Warriors (Immovable block when supported by an orb and a monolith)
10 Warriors (Marches up to a midfield objective)
10 Warriors (Sits back as insurance on me not getting tabled)
ELITES
5 Immortals (Good harassment unit)
4 Flayed Ones (They look cool (Don't worry I'm talking about the old metal ones i haven't gone insane yet

) and can pull a few decent combos)
FAST ATTACK
3 Destroyers (They are great long range support)
10 Scarabs (Great at tarpitting and glancing tanks to death)
Disruption Fields
HEAVY SUPPORT
Monolith (Unkillable and gives me a second
WBB if needed)
Lord goes with the block of Warriorsand deploys centrally with the monolith usually behind them. Destroyers sit back and harass enemy units on a flank. Scarabs turbo boost upfield for a nice bullet magnet and a 3+ cover while Immortals harass enemy on the other flank. Flayed Ones
DS near the sarab blob to support them in
CC (6s to hit can be a rather painful debuff in
CC) with Deciever soon to meet up at the same flank. I use Decivers ability to redeploy to toss the monolith in reserves to make the enemy deploy cautiously and start it on the board to mess with their deployment plans or vice versa.
Thoughts? it seems like a fairly decent list and still fun to play as and against. I'm a tad worried that I made my list too diverse and didnt bring enough of each unit for it to matter
