This is very simple. You can chose almost every possible combination of suits. Just do a super attack with one suit (it has to be an attack than can add a chain attack, obviously), raise your left arm (to switch between the two suits) and add another super attack.
You have to be fairly quick, but this can be done without much trouble. I recommend doing this early on in the game, because afterwards (in story progression) your enemies are getting better and are evading a lot of your attacks.
