I reached legend as of July 32nd with this deck. The reason it is so successful is because of the major tempo plays you can make like Brann + Ancient Shade. The synergy there is crazy.

I will be listing a few cards and why they are so good but I am too lazy to write about them all.

Magma Rager: It's a risk to play but when it lives it really pays off. 5 damage for 3 mana is really good.

Nat Pagle: A strong body that will halt your opponent's aggression. Many times people will concede after you play this.

Nat's Ugly Version: 2 mana 2/4? Plus you can be nice to your opponent and give them cards. It's a win-win.

Argent Watcher: This card is just a 2 mana 2/4 because Priest always uses their hero power anyway.

Murloc Raider: I added a lot of murlocs because murlocs are the best minions in the game. A 2 mana 2-1 is very strong and it synergies with Grimscale Oracle, another great well rounded card.

Lorewalker Cho: Give your opponent Purify and then their hand will be filled with a useless card. Great value.

Wisp: This card has infinite value, it's an auto-include.

Am'gam Rager: Since Magma Rager is so good as an early game threat, we decided to put in Am'gam Rager too. Amazing Confuse combo on turn 5 to get basically another Magma Rager!

Good matchups: Murloc Paladin (because your OP murlocs mess up their win condition)

Bad matchups: Every other deck
