Have yourself or a friend host ranked, team based matches such as Total Conquest and put your skilled friends on your team and play against other random people. It would probably be best to play with 6 players or less so you don't get overwhelmed. Just work together and play your best and hopefully you'll win your first three without having to start over. I do believe Total Conquest would be the best for this as that's how I did mine and I never lost. Have one of your teammates go to each satellite and try to hold it down until the game ends. If the enemy has a hold of one satellite, keep one teammate defending at each of yours and have the remaining teammates go to get back the other satellite.
