I don't know why you'd pick those particular scales. Standard scales for Mari (and I use them quite a bit when I want to play with armies) are:

Order 3, 2 Misfortune, 1 Magic (this can be raised to 3, if you want to depend on high speed research).

Then you have plenty of points to spend on Pretender design, Dominion and Fortresses.

With this setup I depend primarily on xbowmen for my hammer and then Grand Master/Witch Hunters for magical power then depending on what kind of direction I went with my Pretender ( I don't like going fire with Marignon, since they are pretty good on that front) use him to fill the gaps.
