I finally decided to add some thunderwolves to my small Space Wolves army. I don't know how often I'll actually use these guys but they were fun to build and paint. I especially had fun with "Frisbee Wolf". A small magnet in the roof of his mouth holds on to a loop of paper clip in attached to the drone.
I Magnetized the left arms of all these guys so I'd have the option of whether to give them shields or pistols; 'Frisbee''s rider got magnets on both sides so I could choose whether to use a special CC weapon or not.
