3/5 stars. The rules are solid enough and in the right hands can be very powerful, but it does take a bit of thought.
Background.
The Space Wolves arguable had the first act in the Heresy. With twisted orders from Horus, they set about not merely bringing the Thousand Sons to task about their sorcery, but were tasked with significantly more. This saw their numbers significantly reduced by the start of the Heresy, and they became harried by the traitors on a regular basis, and were unable to reach Terra in time for the grand show down. In the background, they are portrayed as a legion apart and and the call of the Emperor should the need arise whilst their Primarch was shunned in a rather similar way to Angron: more like a savage.
Armoury.
Fenrisian Axe is a chainsword upgrade that yields reaping blow. My thoughts are about on par with chain bayonets - it could be useful, and certainly has the rule of cool, but the points cost stacks up faster that you would like.
Frost Blades are an invention of Fenris and generally grant reaping blow on top of your standard power weapons for a large points increase. Arguably the Great Frost Blade is worth the points thanks to S+3 and AP=2 with 2 damage at the expense of I-2.
Pack Thegn is a Prime Force Organization Slot upgrade for an Optae. He gets A+1 and WS+1 with a free frost weapon. This is generally fairly good.
Tactica.
The Hunters Strike gives +2 to the distance of your set up moves which is nice. Perhaps it is not quite the same as the World Eaters or the White Scars, but it serves well for a legion that wants to get into combat.
Gambits.
No Prey Escapes is a way of making sure that one or both of the combatants dies - you don't go to the glory step voluntarily.
A Saga Woven of Glory meanwhile gives A+1 to the challengers comrades in arms if the challenge is won. This is a very nice trigger.
Additional Detachments.
Bloodied Claw gives more troops (they have to be grey slayers) and heavy assault. This is very thematic and on point.

Advanced Reaction.
Bestial Savagery gives you feel no pain at 5+ as a result of being shot at. You then move with a set up and if you get into base to base with the enemy then you are counted as having successfully charged. This is actually strong.

Overall the Space Wolves are a mixed bag. Their core tactica isn't as strong as others, but the surrounding rules are both fluffy and potentially strong - as well as complementing the core tactica. The problem is getting your Space Wolves into range to begin with.
