I have been playing 40k for about one month now with the necrons. My army consists of

40 Warriors
4 Wraiths
1 Deciever
1 Nightbringer
1 Monolith
6 Destroyers
1 Lord
1 Destroyer Lord
10 Scarab Swarms

I normally play against space marines or tyranids. Space marines I can take no problem tyranids though have been giving me issues. It seems like the smaller fast attack units can be sprayed down easily but the hive tyrant and warriors are terribly hard to take out. Any suggestions?

This will either be locked or mover or DELETED!
why?
because LO has it's own strategy and tactics board if you had just scrolled a bit further down.
