Between the three that I briefly had, the build quality seemed to be remarkably inconsistent, and I'm certain that none of them would hold up through extended use. Which is par for the course for PDP.
Make sure you start the session with Palutena and then switch over to Ganon if you want customs distribution to be random. Starting with any other character will tilt the odds in favor of that character.
Do you have to hit targets with Palutena first or just choose her then quit game to switch for Ganon?
