Thoughts? is it even a legal army? general help?

Do I have enough magic protection and casting power? I've got 2 lvl 4s, one of whom has +1 power dice/Dispel Dice and the other +1 power dice. And both have the 'Power of Darkness' spell, potentially adding another 8 power dice.

Should I drop

thanks in advance
