Deck Idea: Play C'Thun, the Shattered as quickly as possible. Most "Miracle" priests nowadays do this with Malygos the Spellweaver. I get this done more quickly by focusing my deck around Lorekeeper Polkelt. Since he is the only minion in the deck, we always find him with Insight. Also, since none of our cards are higher than 4 mana, after we play Lorekeeper Polkelt, we will draw all of our C'thun pieces on the following turns. After we play our 4 C'thun pieces off the top of the deck, we find our C'thun with Insight or replaying Lorekeeper Polkelt with Raise Dead. Extra copies of Raise Dead can have a chance to resurrect C'Thun, the Shattered--vital in some matchups.

The problem: We can't play with any cards higher than 4 mana, and we can't use any minions besides Lorekeeper Polkelt. We also can't play any spells that generate minions like Draconic Studies because that will dillute our resurrect pool, which is already maxed at 2 with Lorekeeper Polkelt and Body of C'Thun. We have a huge issue with warrior too because they can generate more than 30 health easily.

-How to play-

Mulligan: Your 2 most coveted cards are Lorekeeper Polkelt & Insight, but only keep Insight against tempo. Mulligan hard for these two cards, but consider keeping Sphere of Sapience, Palm Reading, Thrive in the Shadows, and keep Raise Dead against control if you already have Lorekeeper Polkelt or Insight (do not keep without).

Play: Early game is best spent searching for your 2 enabler cards. Satisfactory combinations of these include:
Insight + Insight
Insight + Lorekeeper Polkelt
Raise Dead + Insight
Raise Dead + Lorekeeper Polkelt
DO NOT PLAY POLKELT WITHOUT HAVING YOUR SECOND PIECE! He will shove them to the bottom of your deck and you will never see them again. It's possible to discover the spells thru other cards, but incredibly risky. Begin burning through your C'thun pieces, and whenever C'thun is completed, bring him right out. If you are against heavier classes, make sure you keep an extra Raise Dead in hand before you Lorekeeper Polkelt to hopefully double up your C'Thun, the Shattered.

Why no?
Shadowform - This was the card most recently cut. It's needed if the meta shifts more control oriented, but it's too fast currently.
Focused Will - Is useful against paladins but not too much else. Will reconsider if meta shifts.
Draconic Studies - We can't dilute our resurrect pool
Auspicious Spirits - See above

Afterword: Let me start off by saying Priest is probably my least favorite class, and I usually avoid it like the plague. To top it off, Priest is in a miserable place right now, but this has been an EXTREMELY fun deck to play. This is by no means a Tier 1, 2, or even 3 deck, and is a difficult deck that will take some practice.  Although the design space is extremely limited, I would love to hear any suggestions you may have in the comments.
