This is a deck recently featured on an episode of Into The Wild by Willie Dills. It’s something he has tinkered with over the past few years and is a Rank 5 deck, not a meta defining deck.
The point of the deck is to surprise your opponent (they will think you are a Control Dragon Priest) and get some high value shenanigans going with Archbishop Benedictus, Hakkar, and DK Anduin)
