Traitor Guard w/Unearthly Allies 2k

I've been playing around with some ideas and this one struck me as fun. Should work pretty good against anything short of 6+ flyers but here is what I'm thinking:

Traitor Guard (IG)

HQ:

Yarrick - 185

Troop:

Veteran Squad w/2 Plasma, 1 Lascannon, Stealth, & Defensive Grenades, Power Fist - 165

Veteran Squad w/2 Plasma, 1 Lascannon, Stealth, & Defensive Grenades, Power Fist - 165

Veteran Squad w/2 Plasma, 1 Lascannon, Stealth, & Defensive Grenades, Power Fist - 165

IG Platoon

PCS w/3 Grenade Launchers - 45

Infantry Squad w/Autocannon, Power Weapon - 70

Infantry Squad w/Autocannon, Power Weapon - 70

Infantry Squad w/Autocannon, Power Weapon - 70

Infantry Squad w/Autocannon, Power Weapon - 70

Total Pts: 1005

Daemons (Allies)

HQ:

Herald of Slaanesh w/Musk & Unholy Might - 75

Herald of Slaanesh w/Musk, Unholy Might, Steed - 90

Elite:

6 Fiends of Slaanesh - 180

Troop:

20 Daemonttes - 260

Fast Attack:

10 Steeds of Slaanesh - 170

Heavy Support:

Daemon Prince w/Wings, Unholy Might, Musk, Mark of Slaanesh,  & Iron Hide - 220

Total Pts: 995

So what this gives you is a very, very solid fire based that includes 70 models that are all stubborn and will likely be leadership 10. You can always blob squad the big unit and make it a CC beast with Yarrick making it fearless and allowing you to re-roll to hit in the first round of CC. The shooting from the IG portion of the list is a little higher on quality of shots vs. quantity which means I might consider switching to autocannons for the heavy weapons on the vets. And depending on how CC and stuff play out I might drop the fists too. This would allow me to fit in a 3 autocannon heavy weapon team which would increase my range st.7 by 12 shots while only losing 3 St.9.

The daemons provide you with a very fast and hard hitting fist. It's 4 units, all of which have hit & run with tons of rending to deal with those pesky terminators that will be popping up all over.

I think it's pretty solid and would be a ton of fun to play. Depending on how many LR's we see on the seen I might need to plug in some melta bombs on the sergeants but I like it. Thoughts?
