Take both ladders to entrance ramp all the way to the place where the superstars enter, then wait for the other superstars to go to you. Once they get there, hit them all with a ladder and run back with one ladder to get the briefcase. Note: Superstars only walk; they do not run. This trick also works in a Ladder match.
Get both ladders and set one up under the briefcase/title while setting the other one diagonally. Run up the ladder that is set up diagonally while holding the Left and Right Analog-sticks. If done correctly, your superstar will grab the briefcase/title and both the ladders will fall.
