Read it all. Thanks for doing this! Don't get too discouraged by any critical feedback, it's a normal part of the process. Basically every mechanic ever pitched on the Hearthstone team has gone through many, many iterations until it was something we were happy with. Your hero power is an awesome thematic concept, yet it's also fairly narrow. If I could give any advice it would be to try and capture raising the dead within the Death Knight class cards and make the Hero Power something a little more general purpose so the class feels a more open to playing whatever way you want. Thanks for the Monday afternoon read <3.
