What about the hounds? They have a chance of plaguing multiple people at a time and attacking. With 5 defense they're pretty tough to take out, and Grimnak can't chew on them.
Hounds x 2 - 180
Krug - 300

If Krug gets plagued in his start zone at the beginning...who cares?
And of course I agree with Aldin about the knights.
