If you want to boost this plug in a second controller and pick versus. Hit the X button and change it to stock match and one life. Pick a character for both and pick the level noodle shop or one that you can drop off the map and lose then start the match. Walk player two off the edge and you just got a win. Press the Y button on controller 1 for a rematch then rinse and repeat.
Or if you have a turbo give player one, your account the turbo. Once the game is going and set up turbo the Y and rubber band the left stick on controller 2 to either the left or the right and just check on it once in a while or come back in a few hours.
