New Spell Idea

Hello everyone I wanted to discuss a spell idea I recently came up with in the shower.
Spell Name: Rebirth Spell
What it does: Say in a 12x12 tile are you had 13 valkeries die. Then you use the spell in the radius and the valkeries are healed to half health and are now fighting again.
Extra Thing: At the end of a battle if your troops died it ends by it self if you don't have troops except a healer or something. With this spell still left it shouldn't end.

Thank you for reading I appreciate any feedback :D

Isn't this something like the healing spellx10? :O

What if I had 4 witches die, and then brought back to life?? That would be living the golden life. :P

It's common, but there would be a problem if u would rebirth troops like pekka or golems.....

I would just get 5 of the rebirth or resurrection spells n go with dragons. Dragon dead? Np. 3 starts = piece of cake.
