I all I have been reworking my list over the past month or so. With the changes to the ITC I have done some tweaking as well.
So I have 4 list that I have been working on. I lost a game to a guy in the area and he got to pick one of my unit for the next tournament. ??? He picked the Trygon Prime

with the reaper artifact

I recently finished for a local custom model contest. I love the model and don’t mind using him and he’s been effective in the list I have been running. He wasn't my first pick but I can work with him.
So the unit has to stay. I keep my word.
So the list have come up with are below. I’m open to ideas for the list. The first one is the one I think most people will like as it is all offence. The two middle ones are very alike in that they have a solid back field but with different striking abilities. The last, 4 option is closer to the first list with a screening unit included. I think it is more a
TAC list.
The first list is a spam list with 3 Carnifex’s and 3 tyrants. The trygon get dropped behind the Carnifex’s in cover while the tyrants go after the biggest threats. As the Carnifex open things up the trygon has been very us as a counter attack unit allowing my Carnifex’s to get clear of combat and shoot more. Its work well. It is a Null style list so it is week at getting secondary point in the first turn for the ITC missions.
Here the list option 1

List option 2
This list has a solid back field with large 29 man blob of hormagaunts with a 2+ cover save from the Malanthrope. This also allows me to leave my tyrants on the table if I wish to strike 1st turn. I like the Hormagaunts over the termagants as I feel the will do more damage to any unit that gets close for less points. I have had then whip out 6 man units of
TWC with ease.
I have thought about dropping some hormagaunts to get a biovore or two just not sure if it is worth it.

List option 3
This list drops a Carnifex and a drop spore for a Mawloc and a unit of Biovore. I left this list has more tools with the ap2 from the Mawloc. And is better VS Necrons and the new preference fore warrior blobs as it can put a large amount of wound on the unit and halves their saves. I think it would still put pressure on most armies. But if I miss with the Mawloc like I tend to and with the biovores. It is more of a gamble. It also doesn’t pack as big as a threat in the opponents back field when coming in.

List Option 4:
While this list doesn’t have the pure offence of the first list, it still hits hard when it comes in. While giving an opponent a hard choice as what to kill off. With the hormagaunts, Carnifex’s and the trygon prime all saying hello you must pick what to kill before the next turn. The hormagaunts and the trygon have worked well together in killing thing, even WK. I been very happy with them. With the tyrants and everything coming in together in a Tyranid version of an alpha/ Bata strike I can normally kill everything in the zone I pick to come in within two turns. This list tends to do what the first does and be null deployment as much as possible.
