I like MA Jotunheim, but I haven't been all that successful with them, so take this with a grain of salt.

My last was based on W9/N6 sacreds for the initial expansion, then switching to Jarl/Gode and/or Skratti Thugs and trying to get a good blood economy going with the Vaetti hags.
I got into a war too early and then got jumped by 3 opponents. Never got the chance to build castles to pump out cheap the Vaettis.

I'd say the sacreds aren't worth a bless strategy, but the Thugs are. The sacreds are too vulnerable to archers and don't have the killing power. The thugs are very nice once you have a little gear and self buffs for the Skratti. It hurt not to have any access to Earth for hammers and armor.

Trying again I'd drop the water bless, take some earth magic and make more use of the Vaetti, backed up by the Javelin Jotuns and a few of the heavy Jotun troops for expansion. Build forts as quickly as you can and pump out lots of Hags for site-searching, research and blood. Go for Construction 4 early and build dousing rods and gear for the thugs.

Take Luck if you can. 2 of the 3 heroes are among the nicest in the game. Tsatse held off Pangaea practically single handed. I sacrificed Angerboda in a desperate battle to free my capital.
