There may be many ways to beat the arena mock battle but here is mine
First you need a tank, an attacker and a healer. Make sure auto is not set and that initial placement is on. The attacker may have to be Freddy or Lucia, not sure any other may work. Ayaka may be replaced with another suitable healer if you have a better tank. Mont works well if you have Ayaka.
Place units like this:
Always focus on Miranda, dont let her buff, hitting her makes her use cura which doesnt fully heal her most of the time.
Your tank will be hit hard, immortal spirit and sentinel are good, move him to the front
Finish Miranda, then Lucia, she hits Mont hard. If you are not using mont then its not relevant which you pick, but Lucia has a slightly lower HP.
From that point on just heal your units and keep shooting until they are dead.
