Shouldn't the unupped one be a Spell?
In any case, the it's ridiculously overpowered. This+Nova on turn one would lead to way, way too much quanta that's too easy to get. And that's just one. With 2, you become so much faster at getting quanta than any other method, playing a deck with Pillars/Towers is pointless. (Unless it used Fractal, or some other card that requires a lot of quanta to be used correctly. And, of course, to stop Black Holes. This is a lot more powerful than they are though.)
