"Rally" Available Pack Members to an Explore Battle

Howdy, Devs and Players.

Let me start by saying (again) that I apologize if this has been suggested already. I did check the Mastpost and this forum first but, unless I am overlooking it, I did not see anything similar. I also do not have any mock-ups or anything of the sort for this idea either. 

o If you're nearing the end of an Explore Battle and more specifically nearing the end of your health bar (i.e losing the fight!), my suggestion is, when the screen edges turn red, a new option should appear and only if you have wolves in your pack that do not have specific roles. By that I mean Hunters, Scouts, Pupsitters, etc, cannot be called upon. If you have a role-less wolf or wolves then and only then can the button pop up.

The button that appears is one of the two (i couldn't decide): Rally or Howl! Doing so will call available pack members to help inflict one final blow onto your opponent. As for any effects on those pack members, perhaps they'll lose a bit of energy in the attack. As for how much damage the final move does, well, I'm not entirely sure. A Random Percentage? A Set Percentage?

Opinions and thoughts are very welcome! That's all I have for now. Thanks for your time.
