i'm aware of the difficulty tyranids would face trying to eat necrons that keep disappearing, and the necrons are probably the best suited race to fight them (besides chaos). as you say if the necrons lauched a deep-space war against them, as well as their devastating weaponry, the dimensional recall would cause the most harm as it would almost completely rob them of bio-mass to sustain a war of attrition.

but what if tyranids were attacking a planet which necrons were being recalled to? the hive mind may realise at some point this particular threat from necrons and make concerted attacks on tomb worlds, and if they get a foothold on worlds that are dimensional recall hubs then a war of attrition would surely swing back in tyranid favour. obviously any tyranid vs necron war could only happen if there's a distinct lack of 'pop pop popping', so lets assume that's a given in this scenario.

i'm still curious to know if there's any fluff that states one way or the other on necron edibility, if anyone knows.
