This is a Control Priest deck that i have created. I will go over every card in great detail.

                                                                                                                                          Northshire Cleric has always been a powerful 1 drop since its body of 1/3 works decent against some aggro decks to stop incoming 1/1's. It also has its Passive effect giving you card draw whenever a minion is healed.

Shadow Visions is a very flexible card that you can turn into several removal options depending on what your matchup is. 

Spirit Lash Is a great bord clear and healing spell that can be used with Azure Drake giving it +1 spell damage and more healing

 

Twilight Acolyte completely stops early game big threats. It is also a valuable late game minion against control, trading attack with a big minion so that you can safely trade and kill it without having to kill your own minions.

Duskbreaker is great against early aggro as it kills off most minions by turn 4, it also has 3/3 stats giving you board presence after a clear. Overall an extremely powerful early game board clear.

Drakonid Operative has great good stats for its cost being 5 mana 5/6. The selling point of the card is that it discovers a card from your opponents deck, giving you an extra card to play and insight into the opponents deck.

Cabal Shadow Priest is great for stealing powerful minions with the help of Twilight Acolyte.

 

Entomb is best against control decks as hard removal to steal their powerful late game minions. Can also be used with Dirty Rat to force steal big minions.

Archbishop Benedictus is the control card that aims at winning you the fatigue game. the 4/6 stats isn't very good but it does provide a medium size minion.

Psychic Scream is a great way to clear the board that shuffles every minion on the board into the opponents deck. With Archbishop Benedictus you should still win the fatigue game even if you have to use the board clear.

Shadowreaper Anduin is hard removal for big minions and gives you 5 armor. You also gain the Voidform hero power which is either used to kill off minions or eventually kill your opponent.

   

Dirty Rat is used to interrupt otk decks mainly, but it can also pull powerful battlecry minions from your opponents hand nullifying alot of their late game control cards. The 2/6 body also provides good defense against aggro that has emptied most of their hand.

Netherspite Historian is another card that generates a card. The best choices you can get are usually Drakonid Operative and Duskbreaker.

Twilight Guardian is a good defensive minion providing 3/6 worth of stats for 4 mana with taunt on top.
