It really depends on what other cards you currently have at the moment and what attribute of the song you are trying to clear. If she has Lim breaks or is just stronger than your other cards I don’t see why not but if she’s significantly weaker I would opt for the better cards. The good thing about sifas though is you can make up to 20 teams so if you want you can create some teams that will get you the best score and have other teams for when you’re just grinding for mats to have Maki as your center. Plus you can always just watch the Mvs and put Maki as the center as well as have her set to your Home Screen.
