Hearthpwn

I have all 3 and find I use TBK before the other 2 when building decks. TBK is so useful, now that taunts are back in fashion big time. And I don't mean plain ones like Senjin, I mean buffed monsters that get hit with an Argus, can be extremely difficult to remove, without TBK or at least a silence. He will also off the likes of Al'Akir, Sunwalker, Tirion [still gives the weapon of course] - It's a card you hold in hand until the big ones come out. I never waste it on a 2/2 taunt.
