I'm free to play. Is there a chance I can pull Yuzuha if I grind all week for her? I have 80 pulls left

I already no lifed for Remielle (just got her right now after grinding for hours daily), and got Sigrid + Caesar. I don't know a lot about team building but I think I could do Aria, Yuzuha and Remielle, right? If so, I think this could be worth it. I only have around 6 days so it's a large risk, what do you guys think?
