Tomorrow's Event Team Composition

For the event starting tomorrow, since all bonus characters are Virtual Singers and are limited by attribute and sub-unit, prioritizing the event bonus percentage will likely result in most of your team slots being filled with 2-star characters. In live shows, it might be better to use your own cultivated 4-star characters with the same attribute in those slots to earn more event badges. However, in My Only Song, the number of badges you earn is mostly determined by your team's bonus percentage, so it's also a valid strategy to change your team composition between live shows and My Only Song.
