You are not able to change the lineup in battle arena (battle frontier). What they play is partially strategy as well as you are advised to have tactics in lining. For instance like me, I use Swampert (ground and water) followed by Swellow (not a good flying but can help against Swampert's weakness) and then a Magneton (an extra just in case...).
Its there to help the tributes get sponsors for when there in the arena.
you cannot ever beat the battle tower. but if you have completed the sinnoh pokedex then the battle tower will help you complete it. you can battle at the battle tower as long as you want.
