Prestige Star Guardian Syndra

Hello. I hope everything is fine and you are well.

I have been playing Syndra a lot lately and I think I have decided to make it my main.

I Want to Ask You This:

When will Prestige Star Guardian Syndra come to the Store? (I don't remember if it came before this new season. I don't think it did) If you know, I would be glad if you could inform me. Thanks <3
