New Dark Spell: Cloak spell

Just like the archer queens ability, the cloak spell would render your troops invisible to defenses for a short time. Imagine cloaking your hogs from giant bombs(if you're fast enough), or your air troops from air defenses. This would potentially change many of our go to strategies. At th8-9, 2 cloaks could replace a heal spell to get pekkas past those pesky teslas. At th10, 2 cloaks could replace a freeze spell. Of coarse it would have to be a short duration spell, so it wouldnt be too op, but i think it would be a great way to freshen up our army comps.

So if I do decide to take 9 of them in to war, I could get most of my troops to the center of a base without taking any damage?
