So options are....

Dark elf Mystic - MS and mystic benefits
Dark elf Heretic - +1 mana and NM
Elf Mystic - MS + Elf racial bonus + mystic benefits
Faery Mystic - MS + Defensive

I feel like the +1 mana will be neccessary but to miss out on the NM from the dark elf, thats a toughy.
Same for not having a Mystic, A kingdom without MS...

Really struggling to pick. Pennies for your thoughts....
