A War Wolf is pretty tough but really they are only a threat when in a large group. One of them taking on Marshadow is simply not going to be enough. Marshadow is vastly more powerful a single shadow punch should end the round. I don’t see War Wolf getting up after taking a direct hit there. At most this wolf can probably run and dodge for a little while, but ultimately I expect that Marshadow is faster. Marshadow wins.
