Not a bad list. Just a few comments though:
-doom wolves are worthless (except for in wolf deathstars)
-you probably don't need 2 dispel scrolls as your counter magic is already pretty strong, I'd remove one and give that guy black periapt (more ghoul spam

)
-then I'd take away 1 more wolf and buy a 4th wraith, because they can be very brutal but you need a sufficiently big unit so they don't perish from combat res.
