My brother routinely kicks my ass with his Necron list, or some minor variant thereof. Now aside from my nascient skills which you are not allowed to comment on, I would like some tips. What I am looking for is target priority, and then what to target it with, i.e. hit the wraiths first with a shooter, hit the annihilation barges second with assault, etc.

Here's the list and thanks in advance. I am going to start crowdsourcing some of these tips from time to time and leverage all of the knowledge in our community, which is far greater than mine.

HQ - Usually Destroyer Lord
Troops - Usually Warriors w/ Gauss in Ghost Arks, maybe sometimes in a Night Scythe
Fast - Wraiths
Heavy - Annihilation Barges

The C'tan Shard comes sometimes but I usually kill him.

So, we're usually dealing with a Destroyer Lord, Warriors, Ghost Arks, Night Scythes, Wraiths, and Annihilation Barges

If you would target prioritize them and give me the type of unit (assault or shooty) you'd use against them I'd really appreciate it. Thanks!
