[GreenWolf]

I have received two boxes of Space Wolves Venerable Dreadnought as a gift. Now my question is: which two should I build from Bjorn the Fell handed, Murderfang and regular Venarable Dreadnought?

 

My army list:

 

 

Logan Grimnar on Stormrider

 

Ragnar Blackmane

 

Wolf Guard Battle Leader on Thunderwolf

 

Intercessor Squad (80 points) x 2

 

Impulsor (80 points)

 

Assault Intercessors with Jump Packs x 2

 

Ballistus Dreadnought

 

Bladeguard Veteran Squad x2

 

Drop Pod (70 points)

 

Infiltrator Squad

 

Terminator Squad

 

Thunderwolf Cavalry x 2

Absolutely Bjorn and Muderfang. No contest. Bjorn is amazing at setting off Saga of Bear if you don't choose it. Murderfang is just THE most killy unit we have.
