Well if you can storm the turn you enter, you should know by scouting there's a pretty small patrolling force, and you prepare your army for storming already.

Special Monsters Ghost Riders aren't very good at dealing with.
They can destroy army, and you don't care if they die or less cause they disappear.
You get for 5 gems an amount of troops pair at (40 x Wraith, and how many for longdead riders ... uhmm ... a lot). They are active 1 turn only, yeah. But they come suddenly, where you need them most.
And you can cast them as many time as you can!

The wolves costs 15 nature gems, and are an easy deal for PD.
Hawk 5 air gems, and are an easy deal for PD.
Imps and Devil come from 30 Slaves ... and are medium deal for PD ...

And ... if I shoul asset for storming, I should change asset too for special monster and common battles. Oh how I can do ... I'm horrorified about that ...
