Hearthpwn

This is probably to be included in every Priest deck. 

For example, say that we have a 3/3 for the enemy. You play this, and you get a 3/3 and they now have a 1/1. That already is fantastic value for 2 mana. 

This only is bad when the opponent's board is empty, or when it's a 2/2 or worse. But in that case it's not like you're being pressured to play such a card anyway. 

I feel like this card could consistently help you out.  At only 2 mana, it may end up being a staple.  

 Why is the art so smeary ?

Reminds me of the nameless guy: Its good, but does not define a archetype or is powerful. Like that darkmoon card, this card could be slipped into any deck (considering res. priest will be gone). Overall seems good at nullifying big minions but that's about it.

Was really hopping for something with a cooler effect...

Nice to have. But not relevant. All in all priest got nice Cards this set compared to druid imo
