During the battle, if your're losing and need to reset it, copy the URL of the battle window, and click 'reset my battle' for a fresh start.
To change pokemon:
Select the number of the Pokemon from the next drop down, copy the URL of the battle window, and click 'Change My Pokemon' You will then continue with your new pokemon.
After you choose an attack and click the 'Attack!' button, don't click continue. Instead, you can click the F5 key on your keyboard, and then enter if you get that small pop-up. Keep on clicking F5 and enter until you are finished with the match. It makes training way faster.
