Hearthpwn

This is the main deck I used on my climb to legend in April and I went 24-9 with it. I seriously believe that this deck has no real bad matchups and it can beat everything out there

The deck is from BodyBuilder_HS, but I replaced one Glowstone Technician for Overlord Runthak as I'd rather have a 5-drop that is less greedy (+1/+1 instead of +2/+2) but better statted and proactive (has rush). Also I had a game versus a priest where I dropped a 4/7 Runthak, had a couple of  other minions on board too and their only way to clear my board was to cast Hysteria on Runthak. He ended up buffing my hand by a +3/+3 ;)

I really think that this is the best deck in the wild mode right now as it got a lot of goodies in the last rotation. Blademaster Samuro is insane and can single-handedly defeat most aggro decks by clearing a full board and leaving behind a big body. With multiple charge minions as well as buffed minions that are likely to stick to the board for a turn or two, Conviction at rank 2 is a 1-mana Fireball which is pretty insane. Knight of Anointment gives the deck some extra card draw and in particular tutoring some nice buffing spell.

Always mulligan for: Crystology, Smuggler's Run, Grimestreet Outfitter. First Day of School is a great keep if you already have Smuggler's Run or the Outfitter, Salhet's Pride is also a decent keep if you can naturally curve into it. Crabrider is a very good keep in specific matchups, especially on Coin, where you can drop him on t1 and follow up with Hand of A'dal. I might be tempted to keep Samuro if I am going up against something like Pirate Warrior. Finally I always keep Loatheb vs Priest, he has won me so many matchups (vs Priest and Mage mostly)
