Updated the list with cards that work the best for me after Uldum release.
Please ask your questions in comments, I will update this paragraph soon with more info :)
I came up with what I think is a better version, removed Chameleos because of the problem with Zerek's Cloning Gallery and Bloodmage Thalnos because it's not so good for the Resurrect pool. Coffin Crasher is a lot better for both Zerek's Cloning Gallery and your Resurrect pool it and it also help to make space in your hand before playing Bwonsamdi, the Dead. This version just feels even better to play, give it a try if you enjoyed the previous version of this deck.
Thank you all for trying my deck! I read your comments and I decided to revert the list back to my original submission, which, honestly, seems to be more efficient than my previous revisions, so I will stick to it for now while trying to answer some of your questions.
Chameleos is really powerful in this deck. You can use it as an extra spell or as a support minion that you would want to add to your Resurrect pool. This card alone won me a lot of games and even if it happens you won't use it, it gives you a lot of insight to understand your opponent plan and can actually help you to survive long enough facing aggro deck. I understand it's not a very popular card so I'm not saying you should craft it. You can have a look at the previous revision of this list if you want some replacement ideas.
Holy Smite seems to do better than Silence, and can help you to remove a lot of 2-Cost early threats instantaneously. We still need some Silence options, so Mass Dispel is really helpful. I felt like running 2x was a bit too much, but again, it actually seems to be ideal for this deck. It can give you some tempo while saving your life and you even draw a card for free. Played in combination with Archmage Vargoth is pretty cool too!
Hey so here is the situation. I don't know why some of you don't appreciate kiwiinbacon. I'm not a big member of this community and I don't know why you blame him for something nor why all the downvotes. Truth is, I like his work. He featured one of my decks a while ago and I felt blessed to have a guy like this who were able to understand the concept behind the deck I was sharing. I believe that websites like HearthPwn gives us the possibility to share and build new things together. And I'm thankful for kiwiinbacon and his video, because he helps me to show you, HearthStone lovers, that it's possible to find good synergies with cards that nobody plays. That it's possible to have fun outside of the sick metas we always have while still being able to rank a little. That it's still possible to play Priest, despite the nerfs and class identity nonsense. Love to you all, love to kiwiinbacon for understanding this deck and for his amazing work. Have fun guys. Fun is all what matters ✌️ Pym
