This one should be easy to gain just through normal play, but if for some reason you want to speed up the process it can be done in practice mode.
You can do it either by setting the opponent to 'Player 2' control with Rage Art On, performing that characters Rage Art on the Player 2 controller while simultaneously holding 'away' (block) on the player 1 side (easier with a second person to assist)... or you can use the Record function to set the opponent to do their Rage Art then set Repeat Action and begin the playback of the recorded move. Just block for the required number of times and the trophy will pop.
