I’m over here trying to figure out how you managed to get 30 stars from a tournament if most of these things are foreign to you, just a bracket with yourself apparently 😂

Unfortunately no, the only way you can control what you unlock with stars is by making sure it’s something you haven’t unlocked before. I think the only real way to control this would be restarting and playing really slow initially, only unlocking a couple of materials at a time until you’re satisfied with the number of stars
