Hearthpwn

This deck is insane. Takes the aggressive nature of beast druid and slaps a bunch of op jade golems in to the mix. Had a 70% winrate from rank 7 to rank 4.

Strongly favoured against pirate warrior and aggro shaman. I have only lost a single match against each deck type.

Good against all control decks too. Savage Roar takes reno decks by surprise while removal is used up early and can't deal with later golems.

Weakest match ups right now seem to be Rogue. Pirate miracle is better in mid game, and is really strong in stalling to that point with pirates. 

Look for 1 drops, hold onto Mark of Y'Shaarj if you can enable it turn 2. Hold onto golem cards if you have good innervate plays. 

Will write a proper guide if there's interest.
