Sometimes when I go to battle a grunt, I am presented with a recommended battle party. Which is very useful, because I have not bothered to memorize various Pokemon's types or the massive web of what types counter each other. Other times, I am presented with a "previous battle party," showing me the Pokemon I used for the last encounter. The usefulness of which I can't fathom in the slightest. Why would I ever want this? What are the odds that the party I used for the previous fight will be useful against a grunt with an entirely different lineup? Sometimes it even suggests Pokemon who have fainted and I can't even start the battle until I swap them. Is there a way to switch from previous party to a recommended party?
