For this trophy you'll have to perform a Team Ultimate Jutsu Finisher on your opponent, winning the match in the process.
This method will also work if you want to get this achievement at the same time:
For the fastest/easiest way of doing this you'll want to head to VS Battle, under Free Battle Mode and have a buddy, or 2nd controller with you. Now choose Team Match and select your characters. Once the match starts you'll want to use your support characters whenever you can, by pressing LB and/or RB to attack your opponent. Doing this will slowly increase the Team gauge at your top corner side. In the meantime slowly damaging your opponent with your own arsenal of moves. Once you've dealt enough damage with your supports your health/chakra gauge will get a fiery aura. You'll need to press Y,Y,Y, then B to execute a Team Ultimate Jutsu. Now if your opponent has low enough health, to be defeated with this attack, you'll view a memory clip of a successful Team Ultimate Finisher.
