Hearthpwn

You have 2 main ways to win with this deck: hard mulligan for early mechs, control the board until T4; if you have a Frothing Berserker you can win in 2 turns with either your whirlwind effects or something like Replicating Menace. 

Now if that doesn't work, the Plan B is to hold them at bay until you can get one (or both) of your Hero cards online, wherein you now need to steadily gain Tempo until you can finish them, ala Miracle Rogue.  However your defensive options are far superior, so remember that you can be a bit more patient if you can have them use their premium removals.  As always, Grom is your finisher, and should ideally be saved to combo with Scourgelord, although on its own it's still a solid Tempo card, even at 8 mana.
