My problem is discard based cards have been made before. All you did was apply an already thought of idea to a picture that didn't fit it, simply so you could enter a contest.
That being said, it is a good card idea. I'd prefer a different name, picture, and element, but I suppose it's one of the better entries. I could go both ways =/
So what? Discard is a staple of every major CCG, but is completely absent in Elements. Chemist thought of a useful card and made it fit within the confines of the contest. I see no problem with that.
I like this card, but as others have said, it should stack. This, of course, would absolutely destroy a lot of false gods that tend to hold on to their cards (Rainbow, Miracle, Morte, Scorpio, Gemini, Paradox, Destiny... you get the picture). So I don't know, stack or no stack, it's very powerful.
