You're essentially summoning 1 Quantum Pillar creature, if it's "fractal"ed, you get a hand of Quantum Pillars, if it's "PU"ed, you get another Quantum Pillar creature that has the same attack and generates the same amount, 3 random quanta per turn.
I do however understand how it could be a bit OP however. It's supposed to have awesome synergy with Eagle's Eye, but in a conflicting crossroads of OP either way...
One way, it becomes OP because of Parallel Universe, double the quanta production and if it's producing the same amount, that's an instant win for rainbow decks.
The other way, it becomes a cheap and fast, and strong Earthquake...
Perhaps I should raise the N stats, or divide the total quanta the stack would provide by 2, rounded down to the nearest whole number.
