Sorry, freed, but I don't think you thought this through. Ghosts are intangible and cannot 'destroy' in the physical term, as I assume you wish. We have other methods, though less enjoyment to watch, as there is basically nothing 'to' watch.
My god, you can't go around killing dragons like that! *Gandalf uses resurrect on Saphira, who then bites Hulk's head off* *Gandalf then freezes freedman*

*crashes TURDIS into middle of everything*
*kills all your troops, destroys all your weapons*
*you two are lying on the ground, utterly baffled*

*looks up*
*sees all this*
*goes back inside*
*kills all your troops, destroys all your weapons*
*you two are lying on the ground, utterly baffled*
*I step out*
Oh. Sorry, sorry about that.
*takes you on a journey around the universe*
LET US DEPART!
