[Blue Archive] Which Future banner you should Priotize until 6 months from now?

Only 3 banner, Shiroko Terror and Hoshino (Battle). After that, skip any available banner until Kisaki. If you have spare spark after getting these three, try getting the Idol banner especially Sakurako (Idol) as she perhaps the future proof for the next fest that might be appear as SPECIAL DPS
feeling lucky? You might want to try getting S.Izuna, S.Ui and Kikyou but not worth to risk it as they appear before the Fest banner
So, having 48k right now would be guaranteed to get two Fest Students
