Wow. This actually looks pretty neat. I just have some minor fixes to report.
1) Massive Dragons are sort of... not cost-effective. This is a whopping 12
for a paltry 8 damage. I'd just take this out entirely.
2) Gravity Shields aren't critical; you can just take out a second one for a faster deck. Besides, it appears that you're a bit short on quanta.
And that's about it. You can add another Black Hole or a Gravity Tower to bump it back up to 31 cards in case of deckout, I guess. A bit short on quanta, but great deck.
