Deck sucks, shouldnt have this many upvotes

why not run shadow visions to massively improve odds of surrender on madness on 3 which is the whole point of the deck? also bwonsamdi just seems slow and bad same with his spirits, 1 cost copies of murlocs don't evens save that much mana and its a loss of tempo and prevents you from going face in a deck that desperately needs to close out the game quickly. also you had dead ringer in at one point and I thought that was genius to help draw the tastyfin which I actually consider a very powerful card in the deck given its dire need of draw in order to make use of the deck buffing gameplan 

Good effort but it would lose to a LOT of decks.  Druid would destroy this with their armor gain and Spreading Plague.  Tempo warrior (which I think will be a Tier 2 deck come expansion) would clear your board constantly.  You would have trouble with just one Voidlord since you have no way of getting past it easily, so any control-ish warlock is a loss.  In other words, other classes do this board flooding better.

Maybe if you play this deck slow enough, you can lose pretty hard. But if you put many murlocs in first turns, opponents cant defend this. But yeah, it's kind of a problem. Thanks for pointing it out!

Probably could try running Shieldbreaker as a tech card. Don't know how much it would help though.

Why do you use Bwonsamdi, the Dead while you only have 3 1 mana minions?
I at least expected Spirit of the Dead in here.

Either combine those two, or just get rid of Bwonsamdi, the Dead .

Aside this, I like your idea and think there's some serious theorycrafting to do to get this at least semi-working.

Edit: This deck will struggle hard against Warrior and Druid. You either win fast or lose. So I think Bwonsamdi, the Dead is a dead card in here.

Pretty much this.

I would cut Dead Ringer (since it only has two viable draw targets) and one of the Shadow Ascendants for 2 Spirit of the Deads - this way you can fill your deck with 1-Cost minions, potentially buff them with Surrender to Madness and then draw them with Bwonsamdi, the Dead.

Bwonsamdi kinda feels slow in this deck, although it definitely has a great synergy. However, there's no feasible way to replace him with something more efficient and at the same time on par with the card draw.

I like the deck, a lot actually, and since my main class has always been Priest I'm trying this out this evening.

Thanks for advice, changed Murloc Tidecaller and dead ringer for spirits. I forgot about them when i was creating them xd

Bwonsamdi, the Dead will mostly be, as it's name says, dead in hand because it's too slow for this kind of deck..
Firstly you don't have that many 1 drops, secondly you already have enough card draw with Northshire Cleric, Murloc Tastyfin and Power Word: Shield

Waiting on a KiwiiNBacon video about it. XD - Let see if it works!
