Your army list2 still looks like a whole bunch of heavy shooting is going to be levelled against the swarm... I hope you are going to need it!I intend to swarm all over you!
One of my things to buy is going to be the Imp Gaurd book so I can find out what all thise nasty things do.
I also went in to a GW store today (bought a pot of paint) and happened to mention this blog / match up we have organised. The manager was frothing at the proverbial. He said things like: "Classic match up! Gaurds against 'nids, classic!"
I think he approves.
Sleep well... dream of your beautiful world before the nids come and suck the precious life out of it...
