I am also ok with the Firewall nerf, the same with Shrike, also the same with Bitter Endings since it slows down the card for one turn, they did Reios nicely. I am actually hoping for "Ember Oni" nerf as it makes deception decks harder to beat in late turns. Most of the deception decks that I got to battle in Midnight Shadow have "A Toast To Peace", "Cutthroat Insight", "Rapture Dance", "Witherfingers", and "Ember Oni", together they make any deception deck insanely defensive, and if they didn't die before 7 mana it would be hard to beat it.
