Ok so you know how the witch spawns skeletons. The way this spell would work is say you have 100 barbs and 100 archers well when they die raid over? Correct? Wrong with this you can place it in a corner of the base or somewhere you can summon troops normally and for a time period you can revive normal "Larry" skeletons that the witch summons. Wizards wouldn't come back as wizard skeletons they would melee units now look just like skeletons. The catch is that skeletons can't be revived so wall breakers and Larrys can't keep coming back. The number of skeletons per unit is equal to its houseing space.
Pekka =25
Golems=30
Barbs=1
And so on
It will only last a minute and troops that don't die while spell is active don't come back. If they die before or after the spell is over they stay dead.
