When do you guys think Adrift F.Corrin will appear on a L.Banner

Oh I know she's an amazing unit it would suck if she wasn't seeing that I spend 600 orbs just trying to get her on the Adrift banner only to get pitied by multiple shit units with only 1 being good and that being her brother who dispite having +Atk -Def is still a best without a doubt thanks to double Atk/Def bonds, I just want to try to manage to +10 Adrift F.Corrin tho since I told myself that when they release an alt for F.Corrin and put it in the permanent poll I was going to try to +10 her even if she is 5* exclusive, I just hope that if these leaks are real I could also +10 S.F.Corrin too (who sadly is neutral IV but it work's)
