Warhammer 40k Tabletop XXI: Preferred Enemy (Dice)

[Cheesegear]

+3 to seize eh (Since Bjorn gives +1, or was that already counted in there?)?

Nope. Adding Bjorn gives +3 to Seize! Or, Seize normally on a 3+.

Granted if you've got Grimnar's war council plus Bjorn and friends, you're already talking apoc levels of points unless you're unbound, but that's one of the most important times to Seize I would have thought.

Sounds like an exercise!

Champions of Fenris - Grimnar's War Council
Rune Priest; Mastery Level 2, Psychic Hood, Melta Bombs - 100 Points
Njal Stormcaller [either Armour] - 180 Points
(W) Ulrik the Slayer - 145 Points
Iron Priest; x4 Cyberwolves, Thunderwolf Mount - 165 Points

Space Wolves - CAD
Bjorn the Fell-Handed; Helfrost Cannon - 220 Points

Inquisitorial Detachment
Coteaz - 100 Points

Total: 910 Points
In 1750, you've got 840 Points to play with. That's four squads of Grey Hunters in Drop Pods to fill out the CAD. Chuck Bjorn in a 'Pod to make it an odd five. It's not great. But if the plan is to always go first with Drop Pods, then that's what it's going to do.
