Y'Shtola Night's Blessed Deck Advice

Hi reddit, I recently won a copy of the Y'shtola precon deck in a give away at my local game store. I am a bit out if practice when it comes to deck building and would love some advice!

​

I threw together a list on Moxfield. I'm mostly wondering which if any cards in the considering board should replace anything in the main deck and/or if there are other really strong cards I might be missing. I'm targeting ~Bracket 3.
