I figure a good way to make this idea better would be to not have it in Darkness (Or Time, for that matter) to avoid GotP combos, or at least force them into becoming clunky trios to pull it off.
Added a poll to decided which element it should go in. I'm really not sure, with the current theme, that it can go in anything but Darkness. The theme could be changed and the mechanics altered though, if necessary.
