Occurred to me too.
But then it wouldn't have the synergy with Nightfall/Eclipse (Supposedly, due to the fact that there is currently no field-buff for aether/light, we can't know that it'll affect them).
Making the unupped simply free would be alright, it'd probably still get the synergy, after all, mali cells used to.
The card itself, however, is simply one of the best concepts I have seen on the forums. It's laughably simple, has synergy with a number of cards, and isn't something you can just throw into a darkness deck.
