Never underestimate the odds, even 834 quartz might give you a big bag of nothing... I know this well, that's how I got Van Gogh and it was awful.
Oh, trust me, I don't underestimate anything after saving for two years on musashi before the "pity system" came and didn't get a single copy of musashi in 1650 quartz and 86 tickets. I have that memory carved into my mind with fire. I still try to get her but she still dodges everything so that's that.
