Ok, strategies wise, lots of warriors, say 3 full squads, maybe two (thats 60 models if you take the three, lots of tough guys to try take out) so that almost guarantees not phasing out. after that, say 2 squads of 3 destroyers for mobility, and dont forget their guns always glance on a 6. 1 or 2 squads of HDs to provide that extra anti-tank. a monolith is a must for any decent army. take a lord with destroyer body, res orb, phylacetery or whatever it is. maybe a lord on foot too. after that its your choice.
ok, place 2 of the warrior squads on the board to provide a good count so you dont phase out first turn by some stroke of luck for the other player. keep the others in reserve. deepstrike monolith, as it moves other models out of the way. it should survive that turn aswell as dealing out d6 attacks to every unit within 24 inches to clear the area. move your destroyers and HD's into strategic firing positions. keep moving the destroyers to the juciest targets. use the HD's to take out any large vehicles that may hinder your progress or kill your monolith. it should be third turn by now, so bring in you necron warriors from reserve on the 3+ they have a good chance of coming in. use the monolith portal to bring them in, and have them sitting right in the heart of the enemy, reay to cause havoc. after that, clean up the scraps

ohh, put the lord by himself, but always behind another unit so he cant be shot at. have him racing to where he is needed most.
thats all i got for now :wink:
