Needs 6 photons and 6 Nightmares just to start in the first 2 turns, letting the oponent just flood his creatures.
Yes this really would be ideal, but the deck already suffers from not having enough quanta or damage. 30 cards simply isn't enough, and any more you add is simply going to lower the chance of drawing in the first place.
Although saying that, nightmare is kind of useful to have 6 of, as it shuts down the opponents deck with water creatures (assuming he has no water quanta) while doing some damage, and upped photons could be used to fuel a few golden dragons, especially in combination with Solar Buckler. Perfecting this deck is gonna take a lot of work
