Hearthpwn

I'm playing an almost identical list, but with Far Sight and Grumble, Worldshaker, and while it's not needed, I find that Grumble allows for some seriously big jades. I've also considered switching Defender of Argus with Giggling Inventor as it's better on an empty board.

the only problem id have with your second suggestion is the two summoned mechs are going to take up two spots that at that point in the game could very well be a 8/8+ Jade and its also nice that DoA gives you two taunt minions anyway but you are right in those situations where you have an empty board and DoA in hand that really sucks
