This past week kicked things off on Monday with one hell of a Hearthstone patch. We saw 18 cards from the Boomsday project get buffed which brought quite a bit of excitment. With mechs dominating the ladder, its time to see which are the most used.

Thanks to data from HSReplay, we can tell you definitively some cards are more sought after than others. Check out all the stats below and tell us in the comments which buffed cards you are having the most fun playing. Do any of these cards surprise you?
