Oh boy do I have a fun deck for ya'll.

Rank 15 to rank 3 in a day, this deck is a classic snowball deck that is almost impossible to deal with thanks to the recent nerf's to strong rush decks.

Lets talk about some of the key cards of the deck:

Wow I did not expect this card to ever be playable in the current meta, but with the current selection of end of turn priest cards + the insane health buffs priest has to keep other minions alive, its all too easy to get massive value out of this.

Always keep in the mulligan.

Amazing card, part of the system that allows us to snowball out of control early on. Obvious synergy with Drakkari Enchanter. Easy to keep alive with the combo of Young Priestess and cards like Power Word: Shield and Kabal Talonpriest.

Once again keep in every mulligan.

This card is starting to see play in all kinds of decks these days, and really if you think of it it's pretty much a 8/5 for 5 mana, with potential to trigger several more times. Obviously you're starting to see the synergy's this deck is aiming for.

 

I honestly did not think Hogger could pull his weight in this deck when I first added him, but wow is he just a solid card to play. Especially with that synergy for a turn 6 8/8.

The Lich King and Ysera once again if you can trigger these twice that's amazing, otherwise just dropping these on the board gives you some ridiculous power anyway.

The rest of the deck runs a dragon package to even out the curve and provide continued value with solid tempo. If anyone's dishonored your cow recently, this is the deck to avenge him with.

Simple Mulligan Guide: 

Keep all 1 drops and 2 drops (other than Netherspite Historian, you can always get value from this guy later). Always keep Drakkari Enchanter as well. Everything else can be mulliganed to try and secure early game curve.

Simple Play Guide:

Curve your way into victory. There's nothing more satisfying than using every point of mana every turn yet never running out of gas. It takes a little bit of time to get used to the play style of this deck but after about 5+ games you should be ready to start win streaking. Also keep in mind positioning of your minions so you can Defender of Argus well.
