This is a variant of a deck that I got rekttoosoon on ladder yesterday that got me excited for priest BRM decks. It is always satisfying putting together 24 damage from any deck, let alone one that isn't usually about burst, on turn 8 nonetheless. Indulge me and I will show you why you must confess your sins to Lord-Reverend Anduin and pray at the Altar of the OTK!
This deck deceptively curves out as a mostly vanilla control priest sans mindcontrol/deck stealing mechanics. I normally find priest boring as/vs but with every draw I get excited for dropping ET turn 6/7. Then turn 8 loading 24 damage to the face with Velen/Mindblasts. Enjoy!
