Yesterday I took about half or so of this build and changed a few things up when facing a necron player in 1850. I missed a faze out on the third turn by one model, but promptly beat him the next turn. He ran 30 warriors, 3 destoryers, 3 wraiths, 2 tomb spiders, 1 lord, 1 nightbringer, 1 monolith. I had Tzneetch prince, 18 1k sons split in 2 squads, 9 zerkers in a land raider, 3 man obliterator team, basic 10 man squad, basic 8 man squad to hold a control point, and 1 defiler.
Turn one I went first and threw all my lascannons at nightbringer, he took one wound. His turn, he moved up warriors 6 that was about it.
Turn 2, fired all my lascannons at nightbringer again, took off 2 more wounds. Nightbringer was close to one of my son squads, so I threw the 10 man squad in front of the sons to catch him. defiler decided to play melee since wraiths got close, he took 2 out of the 3 but than remained in combat with the single one for the rest of the game... was horrible. He moves warriors again and still they weren't in range of anything. Nightbringer moves in as epected and eats 4 basic marines.
Turn 3, land raider with zerkers pulls up to the 20 man warrior squad and goes to town on them. Killing something like 10 than sweeping advancing the other 10, lost one zerker. One sons squad sprays down the other 10 man warriors, they all go down. Now he was 1 damn model from being fazed so he got his turn. Deep strikes his monolith and some scarabs. Pulls his warrior corpses to the monolith and rezs about 14 warriors. They stand up and rapid fire into my zerkers but only kill 3. His night bringer uses his force blast and kill the rest of the regular CSM.
Turn 4, one of the sons squads walks up to a tomb spider and smacks him with a force weapon killing it. Other sons squads sprays a destroyer squad taking them all. Zerkers rip up more warrios and sweeping advance them again. Daemon prince puts one wound on nightbringer. And than fazed.
1850 match, I lost 10 man CSM squad about 4 sons from one squad from random fire, and about 4 zerkers, so about 18 models. He losts 30 warriors twice, 2 wraiths, tomb spider, 3 destoyers, and a nightbringer with only 1 wound left on it, so around 66 or so models. I do belive I will be useing this build in a tournment, but might tweak it slightly.
