Dojo Mojo: What happens to troops that survive attacks?

After an attack, all troops deployed on an enemy battlefield become lost in the wrath of Dojo Mojo.

Effectively deploying troops to win attacks is a core strategy in Dojo Mojo. Troops are a disposable resource and they should be deployed wisely. Plan out your mode of attack for every battle using the small amount of time before a battle officially begins. 

Deploying all troops in the same location can result in a land-slide victory. On the contrary, it can also lead to your demise, resulting in high resource losses in the long run. Best advice...plan ahead and be resourceful!
