Magic or Education?

Here's the perfect scenario. I generated a map with 8 players initially, and now only 2 remain. The remaining opponent is from the Dungeon faction. The map size is Very Large. I'm playing as Arantir, Vlad, and Lucretia for now. To increase the Necromancer's turn frequency, I want to try a build that includes, among other things, Keen Mind, through Logistics-Scouting and Education-Uncover Secret. And yes, the attack/defense stats are terrible at the moment.
