Myrdin> If you still don't know how to spend your event ticket (blue tickets, not white), you can put all of them on Tachibana. She will never reach the top but, like someone said some times ago, dev may use poll result to make their new version this year (out of the obligatory winners versions). Tachibana is one of the oldest event 5* with no love and no new version. Maybe she will catch their eyes if she gets some love from us.
At least, I preffer to try this instead of wasting tickets on girl with already an alt version/Moneti girls knowing she will not draw them/Anemone.
