Alright, not a bad start, but your list is a little all over the place.
The Wolf Lord, way to much on him and with no
TWC units to back him up, expect him to draw ALL anti-tank fire first turn and do nothing but die.
Skim him down and add him to one of your units.
Something like:
Wolf Lord + Wolf Claw, Stormshield, Wolftooth Necklace, 2x Fenrisan Wolves*
*(You could scrap the wolves even since you'll be putting him to a unit anyways and save the 20pts.)
That makes him much cheaper (180pts, *with Wolves, 160pts without) compared to your original which is 255pts.
The Wolf Guard are fine, but since we're changing up the Lord and how he's going to work, let's split them up differently.
Instead of putting all 4 with the
GH squads, give 2 of them to the Scouts and 2 to the
GH Squads, the remaining 2
GH squads get the Wolf Lord and Rune Priest. Filling them out to their cap of 6 for their transports.
Now, I don't know you're metagame for the armies you'll be facing. But generally speaking Metlagun's on your
GH will do you better then Plasmaguns.
Your Scouts, I would drop the Meltabombs and if you're looking to make them scarey add Mark of the Wulfen to one of them with the Metlagun. Since now you'll have in each of those squads, 2 Melta* shots, 2 Powerfist hits and then 1
MotW. That's going to hurt any squad it comes into contact with and most likely pop any tank you run up on with them.
*(2 shots because of the Combi weapon.)
I would change it to something like this:
HQ - 273pts
Wolf Lord - 160pts
+Wolf Claw,
SS,
WTN,
WTT
(Attaches to the 3rd
GH)
Rune Priest - 113pts
+Chooser,
LL &
JotWW
+Storm Bolter
(Attaches to the 4th
GH)
ELITES - 372pts
Wolf Guard x4 - 172pts
+Combi-Melta & Powerfist (All)
(2 go with Scouts & 2 go with 1st & 2nd
GH)
Wolf Scouts x5 - 100pts
+Meltagun,
MotW
Wolf Scouts x5 - 100pts
+Meltagun,
MotW
TROOPS - 785pts
GH Squad x5 - 155pts
+Meltagun, Razorback Las/
Plas
GH Squad x5 - 155pts
+Meltagun, Razorback Las/
Plas
GH Squad x5 - 155pts
+Meltagun, Razorback Las/
Plas
GH Squad x5 - 155pts
+Meltagun, Razorback Las/
Plas
GH Squad x5 - 165pts
+Meltagun, Razorback Las/
Plas
+Wolf Standard
HEAVY SUPPORT - 420pts
Long Fangs Packs x6 - 140pts
+5
ML
Long Fangs Packs x6 - 140pts
+5
ML
Long Fangs Packs x6 - 140pts
+5
ML
1,850pts
That gives you the 2 extra
ML's, an extra Troops choice, and nice integration of the Wolf Lord and Rune Priest into the rest of your Army.
Hope this helps. Good luck to you in the tournament.
Cheers~
