All Discord ever wanted was a mono light deck and you're all trying to corrupt it with fire ;-;
3 miracles is too many for a rush deck, I'd suggest 1-2. I also prefer SoD over Sanctuary.
This is my opinion too btw. Sanctuary and solar buckler don't work too well with each other either. I would also use at least 10 pillars or at least 3 bucklers, to be absolutely sure you draw your quantum sources. (You could also replace 1-2 blessings with 1-2 dragons, but you'd have to test the quantum balance a bit) Maybe use a morning glory too so you don't let that weapon slot be wasted.
Aside from that, seems alright.
Oh, wait, almost forgot. Pillar/pend split
