If you click on previous grids it'll show you your rarity scores for the ones you've done (at least on that device).
9/9 score of 17 today which was definitely my best.
I have 2 transactions left, I definitely need to use one so I might as well use both:
Drop Ohtani, add Schwarber
Drop Arozarena, add Yordan Álvarez
I should be fine cap wise, I think I'm pretty low.
Also, screw it bench:
Drop Tatis, add Gunnar
