Hearthpwn

Straightforward Elemental Burst deck I threw together. Low sample size, but so far seems promising. Managed to beat three Mages and a Control Warlock (he played Tickatus, didn't save him) in a course of 20 minutes.

I started building this deck around Ysera + Al'Akir finisher combo, tossed in more Windfury targets and topped it with a bit of spell burst to close out the game.

Mistrunner is looking very strong in this deck. Thanks to copious amount of Windfuries, we're likely to have good targets readily available. Notetaker works super well with Guidance and Devolving Missiles and with Portals in a pinch. Kindling Elemental also feels strong in this deck, getting an Arid Stormer a turn earlier seems to mess up slower decks.

I opted to leave out Gyreworms and replaced them with spell burst + Gidra for another high-threat Windfury minion. We don't have high cost spells to make ginormous Gidra in one go, but between Mistrunners and Whack-a-Gnolls it grows large enough to warrant attention.

EDIT 1: Swapped Rune Dagger for Wandmaker. Dagger wasn't doing much (even in terms of Custodian redundancy) so I swapped in Wandmaker. Shaman has solid list of 1-mana spells & 2/2 body just generally seems better than a mostly plain 1/3 weapon.

Currently rocking a 75% WR 18 - 6:
6 - 0 vs Mage
5 - 2 vs Warlock (both losses vs Soul Shard Control with plenty of removals/wipes) 
2 - 0 vs Rogues (haven't faced many)
0 - 2 vs Priest (unfavored, but doesn't feel unwinnable)
1 - 2 vs Paladin (prior to Wandmaker, haven't seen many Pallies yet. Surprisingly)

EDIT 2: Took out Firebirds as they're proving to be win-more cards. I decided to toss in a Tour Guide for extra 1-drop and Kazakus because now we have no other 4-drops. This helps out with Face Hunter decks (something my previous version was struggling with) while retaining an even matchup vs paladins. Doomhammer adds more in-hand bursting potential, long as you've got ways around Taunts it's guaranteed 16 face damage by itself.
