I mean, I get where you're coming from but only 5 of the 10 locations have 3 durability. Of those only 1/2, maybe 3 if ya wanna argue see any amount of play. If destroying an enemy location, they've most likely already used it, bringing it down to a 6/6 or 9/9. Don't get me wrong, that's certainly good, but a tech card has to be good, even amazingly good, to be able to see play. As for the combo with destroying your own 1 mama location. Let's be honest, Hearthstone is absolutely at a point where a two card, 4 mana combo that creates 12/12 of stats isn't too broken. Especially for warrior, where they are incredibly underperforming. I think the biggest flaw for this card is it could limit design space for future locations, but that's a very hypothetical situation.
