After above roughly 60 pulls in Sage Naruto Treasure (my bad luck) I've gotten Ao. Is there still a possibility of me getting Sage Naruto and if so how many more pulls roughly should I put in?

I've also gotten my first (Onoki) from Five Kage Treasure. Should I save my seal scrolls for a rare from Five Kage or go all in for Sage Naruto?

Any response is welcomed, thank you.
