Yeah, there's pages and pages of negative feedback about this card. Zanz hasn't ever responded to any of it. Keep in mind that this game is developed by one person, in his free time. He was somewhat active on the forums when the last version update came out (1.31) but he hasn't been active since then. (or at least hasn't done anything more than lurk) Most likely he's been busy with real life and his actual job (he gets nothing from elements other than maybe a bit of advertising money and the occasional player donation for shards) and probably hasn't seen most of our complaints about it, or else hasn't had time to do anything about it.
I do feel your pain, though; it's frustrating to have to design every deck based on the rather large possibility that you're going to see this card used against you. Unfortunately, there's not much that can be done other than 1) pack counters in every deck, like mind flayer, lightning, etc, and 2) abuse the living hell out of it vs the AI while you can.
