Arras prophet looks a little weak, I don’t think you’ll draw plumes reliably. I would play Aethermaster for the value of the replaces and then slip Kron in there. Maybe I just like Kron too much but I would play Aethermaster over Arras Prophet with or without him.
I might go further and exchange Gloomchaser for primus fist, vellumscry for Spelljammer, priestess for Bloodbound Mentor and drop inkling surge and maybe drop one deathfire crescendo.
To my surprise I also found punish to be generally a slightly better choice than sacrifice In S rank at the moment so you might be interested to try that.




It was supposed to be there (it was in some earlier versions too). I think -2 Inkling -1 Mindlathe would be the way to go.
(not even talking about Plasma Storm and opponent’s rain on our parade). Although the Gibbet+positioning tools subset is an OK addition to a control deck.
