There is one method that can help you save resources on campaign mode, you can try this

5 card decks, only one card is full soldier and the rest is 1 soldier, so when you face more than 1 enemy, hopefully they attack those with 1 soldier first, and if you get AOE by enemy(which hurts a lot), just close the game application and return, battle should state draw, your soldier won't be reduce(I think still works)

for Mia that you envolved badly, it's fine, as long as it's not the jewel you spend on getting and envolved badly which I did a one month ago, lols
