Land Raiders are sort of a mixed blessing in low points. At 1000 points, not much will be able to deal with them...but you could also lose 25% of your army to a lucky lascannon shot.
If you're looking for anti-tank, you could have
two slightly smaller squads of Long Fangs (5 marines, with 4
ML's) for cheaper!
In addition to that, something that should probably be done either way - give those 10 Grey Hunters 2 Meltaguns. It's 5 points for both. More anti-tank, anti-elites...and for 5 points!
Blood Claws are fun to use, but Grey Hunters are much better. Even in assault, thanks to a 10 pt Wolf Standard, the Grey Hunters can do at least as well. Not to mention, the extra
WS and bolters.
Your
WGBL is way too expensive and way too fragile. 150 points, and he dies the same as any two wound marine. A Rune Priest would definitely be more effective. However, if you're looking for a combat character, take a Wolf Lord with minimal upgrades...maybe a Frost Axe and meltabombs.
I would consider something along these lines:
Rune Priest
9 Grey Hunters
- 1 Meltagun
- Wolf Standard
- Mark of the Wulfen
- Rhino
10 Grey Hunters
- 2 Meltaguns
- Wolf Standard
- Mark of the Wulfen
- Rhino
5 Long Fangs
- 4 Missile Launchers
- Razorback with Las/
Plas
5 Long Fangs
- 4 Missile Launchers
- Razorback with Las/
Plas
All of that is only 880 points, so you could add some Land Speeders or a Vindicator or a couple
TWC. Of course, all of this is assuming you want to go with a "competitive" list. If not, feel free to ignore this
