1. You need to know which neutral creatures can have +1 morale.
With +1 morale for neutral creatures, the probability of a double turn is 4.2% - for one stack! If there are 7 stacks, the probability will be around 30%. That is, you attack such neutral creatures three times, taking into account that at least once they will double-morale ;)
And you didn't say anything about artifacts for anti-morale and magic of Sorrow ;)
Use them if you can :)
