How does Monster Storage and Substitutes work?
The following is taken from the manual: Monster Storage: Monster Storage is a place to keep the monsters you scout. Monsters in storage gain experience points as you fight, though not as fast as substitutes, and far slower then active monsters. Substitutes: Monsters can be set as substitutes who will accompany your active team. They can be switched into the team at any time outside of battle using the Substitute command.
