Editing Warhammer 40,000/7th Edition Tactics/Necrons (section)

===Buying & Collecting===
The best and easiest way to start is the Battleforce + Catacomb Command/Annihilation Barge combo. This nets you everything you need to play a decent match at 700-900 points depending on how you set up your vehicles and Overlord. The trick is that the Command Barge comes with what amounts to a free HQ character in the included Overlord. That Command Barge alone is one of the best deals out there in the entire Games Workshop lineup. Alternatively and with Start Collecting! boxes you can start with one Overlord, 12 necron warriors, 3 scarab swarms and a Triarch Stalker, which seems like it's going to be the replacement for the Battleforce box.

'''HQ Choices:''' 
Your best bet will be a generic Overlord. One of these guys decked out in the right wargear (sometimes riding a Command Barge) is probably the most popular HQ selection. Nemesor Zahndrekh is pretty much the most useful named HQ in most circumstances, now, what with his bag or tricks. If you're looking for someone to lead your combat Deathstars, Vargard Obyron, Orikan, and the Destroyer Lord are your guys. Anrakyr isn't all that great anymore, and Trazyn is now garbage, thanks to them not giving him objective secured and removing his ability to take over Lychguard bodies (do you REALLY want to be losing your fully decked out Overlord just to bring Mr. Useless back from the dead?). If you're going on the cheap, just take a naked Lord and hide him with Immortals. Alternatively, you can go with Szeras, who may potentially boost a blob is the dice gods favor you with a +1 to toughness. Imotekh is a LoW, now, so you'll only be seeing him in the higher points games... he's not bad, though.

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.)

'''Troop Choices:''' Warriors are dependable and you can have many of them. Problem is, your opponent will most likely charge them as she/he/it 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:''' Most of these are on the lower end of mediocre, but there are a few exceptions and niche uses for them. Deathmarks are your best bet to start out with, since they're good at taking out MCs/heavy infantry that the rest of our army has problems with. Lychguard are alright in larger games when you have a combat Overlord who needs an escort (Trazyn, Obyron, and Anrakyr are good for this)
and as tempting as the Warscythes are, the Sword and Shield is usually the better call. Triarch Praetorians are terrible, and you should avoid them. (Usually, but they can give you some needed mobility in mid point matches!). Ditto for Flayed Ones. (Not correct anymore, they can be very hard shock troops if you look at their point/power value in the current codex!) C'tan also suck, but are fluffy and can be entertaining if you want to try out a Tremor-Crons list. The Triarch Stalker is a model you'll either love or hate. It's twin-linking is useful, but only you can decide if it's worth the points. (It IS worth the points, but usually a #1 Target.)

'''Heavy Support choices:''' Monolith is 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, but are also the biggest target. 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 shit at destroying vehicles, although they will come for free basically with your Warriors. Wraiths are realistically the best combat unit Necrons have. Take them if you have the points, or if you want a threatening counter-assault or deep-strike melee threat. Destroyers are great, too (sorry Tomb Blades, it's just too expensive to make you good <- this is bullshit due to their lower costs in the latest codex. Field them if you want. They are the only Necron unit that can cheaply ignore covers.). It's hard to know what to take and what to leave from this section.  Unless you're going with scarabs and spyders, pick your Fast Attack slots to cover and complement your other choices, not the other way around. 

'''Transports:''' Catacomb Command Barge is considered one of the greatest vehicles in the game. No exaggeration. If you've got an HQ with 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. (NOPE. They can only be added to warriors - min. 10 per group - and carry max. 10 models. So if you don't want to waste turns entering it, no way to get a stronger squad with a character inside.) 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. (Of course, they will have to fire Snap Shots unless you move less than 24").
