Eh Its just a gimmick though imo. If you are actually trying to win then I really wouldn't use it, but if you are just playing for fun and to test things out sure. But you're spending the entire game to get the perfect cards to do this combo, if they have a few taunts or you're against zoo, you're ****ed. Just not a huge fan of it personally.
Mind vision eh, it could be a really awful card you get, when I'd much prefer another Shadow word: death or something. I understand the combo though, just not sure why you use two gadgetzans Silence I really don't understand though. Breaking taunts? Plenty can do that. Shadow word pain/death, hell even an owl, then you have a minion for them to deal with.
