Ruckus Rumble

Minimum requirements: 3 players, 1 controller.

Set up a match with 3 players total and position the two alternate accounts one in front of the other. Now all you need to do is position your main account in front of the other players, facing towards them, and hold to charge up a Guard Breaker attack. When you release , you will lunge towards both of the other players and hit them at the same time, whereupon this trophy will pop.
