Hearthpwn

This deck has been really good to me due to it's insane match-up with any flavour of Odd and Even Paladin. Paladin cannot stick dudes to the deck no matter what they do and the powerful aggro tools decide games by turn 5/6 before Paladin has any chance to out value you.

The other popular class of the moment is Warlock, in particular Cubelock. This is a tougher match up mainly because of all the clear and healing that the traditional Cubelock packs. However a less than perfect draw from the lock will allow you to get quick wins. If they don't draw Defiles and Hellfires you have a great chance to pop them by turn 5/6 before they can put together all their combo pieces. If you get a Frothing Berserker down on turn 3 and they can't remove it immediately then you're a massive favourite.

Combos to look out for

Frothing on board, play Leeroy and a 1 damage AoE for huge burst

Coin Woodcutters Axe into turn 2 Redband Wasp for a 3/4 with Rush on turn 2 (and other similar combos)
