I'm back! My Nids list

This marine is so fucked.

Here's what I'm going to roll with this weekend since I'm still missing my Flyrants. Keep in mind that this list can be well-equipped in a huge number of ways to fight different metas. It just happens that I play in a pretty MEQ heavy meta and this list is more casual than for tournament play. However, it's still pretty mean with all things considered. There's a huge number of psychic potential and T6 wounds in this list.

1850
14 kp

HQ:
Swarmlord = 285
Hive Tyrant (Strangle, Reaper, Adrenal) = 240

TROOP:
10x Termagaunts = 40
10x Termagaunts = 40
10x Termagaunts = 40
10x Termagaunts = 40
10x Termagaunts = 40
10x Termagaunts = 40

ELITE:
3x Hive Guard = 165
Venomthrope = 45
Venomthrope = 45

HEAVY:
3x Carnifex (TL Devo) = 450
Trygon = 190
Trygon = 190

This can be re-adjusted to take Mawlocs, in fact, it'll drop your list to 1750 exactly. This gives you 2x Tyrant Guard if you so choose. Another variation would be 1x Mawloc and 1x Trygon Prime for added Psyker hate.

The biggest thing to note in this list is that I'm walking just about everything. The way this list will be successful is by interlacing infantry and hiding your Venoms behind the wall of Fexes. Cover is pretty easy to come by, and even your most basic Terms can get cover if you use a dotted formation to mix the squadrons and maximize on cover. Swarmlord and the other HT can get cover from the Fexes, and the two Trygons will offer a lot of deadly options for your opponent to shoot at. In total, you're looking at 39 T6 3+ wounds through Shrouded cover that your opponents need to chew through to.

Just don't pop out your Trygons like an idiot, the 2+ reserves from Swarmlord should help. Play with 4x Term units for starters and then reserve 2 to backcap points. Keep the Venoms separate because your opponent will have to waste fire at one without wounds carrying over the other.

Oh, and I don't care about flyers much.  You can ignore them just fine, but if they don't down your Fexes, they'll be walking into a no-fly zone.
