I am actually running a very similar deck I brewed up recently (I can upload it to this site if you'd like), and I have a few suggestions for you. For starters, a single playset of divedown doesn't seem to really counter all of the removal in this standard format, and i frequently ran into
Bontu's Last Reckoning when running this deck, for which a few spell pierces will do the trick. Another important thing i found is that Lightning Strikes or at least Shocks were almost always necessary to finish the game when the opponent casts removal you can't answer or be used as effective removal themselves (in most situations Lightning Strikes are better than Shocks). I'd suggest putting the
Abrade s into your sideboard because at least in my experience, you won't come into many decks that will use in the first round that will really harm you. Lastly, what benefits do you think you're receiving from running
storm the vault and
prying blade? I know this whole deck is quite janky, but trying to jam in that combo in at the last minute seems like a bad idea.
