No, I’ll still play with Priest, but it’s looking more and more like Rogue might be the way to go.
Keep in mind this is not a counter card in one class. Rogue very often gets Mage spells through Wand Thief. And this card alone pretty much counters most of the Priest Hero. With Mage having access to this and devolving missiles, it’s really going to make Mage a polarizing matchup.
Priest really suffers from massive polarized matchups. Warlock and Mage having an 80% win rate vs Priest does not bode well.
I’ll definitely be giving it a shot, but it’s very likely that Priest won’t be able to compete unless they have some sort of way to counter their polarized matchups.
