I agree that it's over-tuned. So much so that basically everyone that plays with it (or against it) immediately recognizes it. In normal circumstances, I don't think it makes it out of PTR to live play. Now, though, they are releasing multiple shakeups, and one of the driving themes is to tip the balance back towards slower decks. They may let this one go live only to then nerf it in one of the subsequent patches. Who knows?
