This is, in my opinion, the exact kind of card time needs. An affordable mid range attacker (and more) that works well within its own element. This card could make mono-time one step closer to being a stand-alone element. Just as well, this card would work well in other duo, trios, etc.
I have to say this is my favorite idea from you so far, not necessarily because it is the most clever or conceptually strong, but because I think its needed rather improving an already well-to-do element. Awesome idea, + karma.
