Based on the fun "Form of the Dragon" card of magic, this deck is all about trying to make the majordomo a good card, as well as resurrect, with the long term goal of recurring majordomo and resetting to 8 health. Fortune would have it that majordomo is already an extremely beefy guy and that resurrect  is a far better card than it would seem to be.

Let's go over the game plan: we hope to win with either a Kel'Thuzad, a form of ragnaros or through boring old board control. For any of these options, we need to dominate the board. Let us go through our plan to do this:

Early game: Between Northshire clerics, Loot Hoarders and Annoy-o-Tron we have plenty of early interaction with our opponent. Two of these should draw you a card. With the Power word: shield and the Velen's chosen we can even make these into significantly more annoying threats, and we are fine with having any of these silenced really.

Mid game: The three couples of Dark Cultists, Emperor Cobras and Piloted shredders are how we will gain board control. None of these threats are things most players can ignore. Why the cobra you ask? Well, it is a superb resurrect target and it acts as our removal in this deck. We also play two tech cards: the mind control tech versus any swarm deck and the big game hunter because Dr Boom is still in the format, plus he doubles duty with the Majordomo.

Late game: Sunwalkers and Emperor Thaurissan are key here. We are very strong in the late game after all. All three of them buy us time in their own way for us to play our cards. With the resilience of the creatures in our entire deck and our own ways to gain card advantage, we should be able to win easily from this point.

Some card choices:

• Mass Dispel: Cantrips and we do need an answer to Tirion, plus I always seem to find good targets for this spell.
• Holy Nova: We need to leverage the northshire clerics, plus it is a great spell to retain board control. And it deals with many aggro decks. We even have the spellpower. What is not to like?
• Resurrect: Each creature in here except for the BGH and MCT is great to rebuy. The only thing to watch out for is that your graveyard does not get polluted by sheep or frogs. Against shamans or mages I recommend burning this card early and aggressively.
• Majordomo Executus: Some decks cannot win against the deathrattle on this guy. Funny if you get to rebuy him with a Kel'Thuzad or resurrect, because you will keep resetting to 8 life. The one thing to watch out for is burn, because with our taunters we should be in the clear against creatures.
• Thoughtsteal: Another way to leverage the late game and chew our opponent out through hard card advantage.

Why was this not included?

• Injured blademaster: considered him, but I do not like him over our suite of three drops and I don't want any more three drops either. He works well with resurrect, but he's dead against warriors, which is not an easy matchup for this deck.
• Piloted sky golem: I prefer sunwalker over these. Maybe if the deck didn't contain the Majordomo's plan, I could see including them. The taunt is more key to our strategy.
• Sylvanas, Cairn Bloodhoof, Hogger: Don't have them, but they could definitely be good if you could fit any of them in there.
• Lightbomb: Could replace the Holy Novas, but then you should reconsider including Northshire cleric. We need the card draw to make this deck work, and I don't like cutting our creature count for these because we want board control, not board reset.
• Auchenai: Does not fit the game plan. We don't need them as our source to grind our opponents out anyway.
• Prophet Velen, Ragnaros: I do enjoy 16 damage hero abilities, but I simply do not have them and while funny, the prophet is overkill. Ragnaros could be considered.
• Mana wraith, Shade of Naxxramas, Wild Pyromancer: These could be considered for the early game, though the shade is just another late game tool really. The mana wraith was tested and while it performed well, I just needed more taunts in my deck. The wild pyromancer was fun in the deck as well, but I just didn't think he did enough to justify the deckspace.
• Ysera: Yes, She would be amazing in this deck. If you are to consider her over the far more risky and hilarious Majordomo, I'm sure your win percentage will go up.

Matchup advise:

Aggro: Easy matchup. Between the taunts the healing and the holy nova and the very annoying mid game creatures they will have to spend too many resources dealing with your cards and will rarely get your life total low enough.

Combo: We have a couple of good combo breakers, plus our deck does not really give them a lot of time. If the combo is burn oriented, I suggest applying the maximum of pressure that we can, because we can't survive through Alexstrasa plus burn spells if they can afford to keep their burn in hand.

Warrior control: Don't play into the brawl with too many non-deathrattlers. Against warriors we need to capitalize on the divine shields and piloted shredders with our buffs and resurrects.

Other control and midrange: They should not have enough removal to deal with our minions, and we do not need a lot to keep the board control in our favor because we are playing a priest deck.

EDIT: I've gotten great success with the deck thus far, and after a while I kept running into classes that can easily deal 8 damage without going through taunters, plus it seemed that the majordomo was usually overkill when he did come out. I've replaced him with a mind control, because all I need is another piece for use against control warriors in here. I will come back to the majordomo, but perhaps as part of a mage with ice blocks and alexstrasa.
