Hearthpwn

Good thing this one only has 20 Health, as it can be quite difficult.

Main threat of this guy is Blood Beast as it will undo your damage, don't be afraid to use your weapon to kill this, though you'd prefer not to of course. Most usefull cards are:

• Arcanite Reaper
• Brawl can be skipped, but very usefull in dealing with a growing/taunt board, which is bound to happen if you focus on attacking his hero 
• Sul'thraze Not absolutely necessary, but dealing with one or two minions before going face can help stabilize
• Heroic Strike Vital, as it will boost your weapon output greatly. Don't use without a weapon!
• Forge of Souls usefull for getting those weapons from your deck
• Execute

The rest is optional and for keeping your hero alive or dealing with the growing board.
