Editing Warhammer 40,000/5th Edition Tactics/Necrons (section)

===Buying & Collecting===
Just start like with any other army; an HQ, 2 Troops choices, 1 vehicle, and a Fast Attack / Elite choice (easily done by buying Battleforce and a Command Barge). 

'''HQ Choices:''' 
Your best bet will be a generic Overlord. One of these guys decked out in the right wargear, riding a Command Barge, is probably the most popular HQ selection. Anrakyr, Trazyn, and Nemesor Zahndrekh are all somewhat decent HQ choices, given the right circumstances. Vargard Obyron, Szeras, Orikan, and the Destroyer Lord, not so much (they're more along the lines of support HQ choices). 

Keep in mind that Necron HQ and the Royal Courts they can unlock are incredibly good at buffing your army. Whether it be Anrakyr's Pyrrhian Eternals, Szeras' upgrades, or the Overlord's Phaeron ability, each HQ is tailored for both specific tactics or general enhancement. (Don't start out with Imotekh though. Sure deep striking Flayed Ones may seem nice, but the Stormlord's abilities are grossly overrated (more coming on that later.) He's more useful in larger points games where there's more immediate targets for the enemy to deal with.)

'''Troop Choices:''' Warriors are dependable and you can have many of them. Problem is, your opponent will most likely charge them as she/he will know Warriors die when assaulted. Many will argue that Warriors is the way to go, while others praise the Immortals more. Truth of the matter is, you need both. Your Warriors should be your objective holders or mid line support, while your Immortals should be at the forefront capturing contested objectives or taking the fight to the enemy (better done with Anrakyr's upgrades.) Use both Troops choices.

'''Elite choices:''' Are okay, but should be considered for bigger point games. If you're starting out use Lychguard with swords and shields, because they gain an invul save (and that's something they'll need, epecially with all the armor ignoring weapons out there). Warscythes are great against mech armies mostly, so reserve those for that. Triarch Praetorians are average, and are best when armed with the particle caster and voidblade (you get more bang for your buck out of that). Flayed Ones=no. Deathmarks=not unless you take Harbingers of Despair, too. Triarch Stalkers are mostly good, but you need to take 2 of them so they can be effective. Redundancy is key with them, especially since they are so multipurpose. C'tan Shards should be avoided unless you've got a specific plan in mind for them.

'''Heavy Support choices:''' Monolith. Tough, but not recommended for low point games. They cost a lot but can do a lot, too. If you absolutely need it, take only 1 (for now). Spyders are decent in close combat, but they're best served in a support capacity. Good for both repairing your vehicles and spawning more Scarabs. Doomsday Arks are powerful, but fickle. Doom Scythes have the strongest weapon the Necrons have at their disposal... mounted on the weakest vehicle. If you absolutely have to take it, take two. The Annihilation Barge is one of the best units in the codex. Spam them, if you can.

'''Fast attack choices:''' Arguably the best section in the codex. Scarabs are excellent at destroying vehicles, and they will come for free basically with your Warriors (if you have Spyders in your army, go crazy with Scarabs). Wraiths are arguably the best combat unit Necrons have. Take them if you can. Tomb Blades and Destroyers are great, too. It's hard to know what to take and what to leave from this section.

'''Transports:''' Catacomb Command Barge is considered one of the greatest vehicles in the game. No exaggeration. If you've got an HQ how has a Warscythe, get him on one of these. You will not be sorry. Ghost Arks are great, but are for Warriors and Characters only. Keep in mind they can only fit 10 models inside, too. They're nice support if you're fielding lots of Warriors. The Night Scythe is for everything else. Move them flat out 3 feet into the enemy and unleash 10 Immortals with a barrage of fire. 

*'''UPDATE:''' The new Necron Battleforce is now available. It brings 5 Immortals, 20 Warriors, 5 Canoptek Scarab bases, and a Ghost Ark. This is a great way to start. Don't buy it from Games Workshop, though. That'll cost you 105 dollars. Find it online for 25% off and you'll have yourself an easy effective start to your army. The Ghost Ark can only carry 10 Warriors which is half of what the battleforce brings, so either have them all on foot with the Ghost Ark floating along side to replenish fallen Warriors, split them up 10 by 10 (half in, half walking), or perhaps the best combo, 5 in and the rest walking. 5 Immortals isn't bad, but is your only source of mobile heavy firepower. Sure the Ark can be made into a Doomsday Ark, but don't. You'll lose your transport (unless you go through the pain and wonders of magnetizing... but even then, don't brink a Doomsday Ark to a low point game). 5 Scarab bases is nice, since the only way you can normally get them is through Warrior set boxes. 
**Grade: B+ (pro-tip: buy a Command Barge with this and you'll have a playable army that will actually be able to perform decently).

*'''UPDATE 2:''' Second wave is now out, some of the models are very nice indeed. Night/Doom Scythe are now out as well.
