I have to say Space Wolves are kinda cheesy. Not most of the army, but primarily the Rune Priest.
I play using the pups. I played a 1k match that was me vs 500 nids and 500 Tau, using a sing FOC between em. The nid player had mostly Fexes, and 2 genie squads and the tau player had a broadside and commander with retinue. My priest, first shot he got, used JotWW and lined up 2 fexes and the broadside, killing them all on turn 1 or 2 (Cant remember which) which was a very large part of their army.
Even though I love him, Rune Priest=Cheesier than Cheeze-its
