This+Fractal+Ball Lightnings. Assuming ideal conditions, 8*4 for this card is 32. Another 8*5 for the Ball lightnings. You've just dealt 72 damage in one turn. Depending on the cost, you could easily run aether towers and splash whatever element you want this to be as your mark.
I'm not particularly fond of the mechanic at all, but just thought that would be an interesting idea to point out.
