Hehe, well, the game level aside, where I love to joke around - just for me to understand the effects of the globals...
- noone has any
direct advantage of it, other than maybe not being affected in comparison to the others
- the more units+provinces one has, the more one is affected
- nations with old mages are in a bit of trouble

, while nations with undead or undead summons won't need to care at all.
Of course Marignon is not really the target, since he's almost dead now anyway (I'm not claiming it's going to be easy to storm the castle, but his armies and income base are dead), so it's just about Man and Abysia - where the latter one has a few mages which might be a bit on the old side...
