Here is a possibility for another unupped counter to Neptune.
I have been playing a modification of Xenocidius's deck against Fire Queen (http://'

Use Aflatoxin on a Firefly, OTK for the win.
I added a second Aflatoxin because not getting it until late sucks, and probably would be worse against Neptune. I also took out one Phase Shield and replaced it with four upped Sundials, which makes the deck larger but makes it play smaller. You do have to make sure you are not stuck with a Sundial at the end when you want to play your combo and attack. I have also been experimenting with having another couple of different shields in the mix for the early game.
Looking at Neptune's cards, I decided that this same deck should work against him with the addition of a second Fire Storm. You only get six Condors instead of seven because of the extra Fire Storm you need in your hand along with the Sky Blitz when you play the fractal, but all his creatures die. I hit him with six 48/25 Condors.
This is the deck I actually played against Neptune, although the Antimatter turned out to be completely useless, because I got an Aflatoxin in my opening hand which I played on his first creature, an Octopus, and by the time I played antimatter on a dragon two turns later, I never let him attack. I put it in in case he got an early dragon and I drew it. It didn't stop me from getting an easy EM. I was only on my second Phase shield with 4 cards still left when I had the entire combo and won, and two of the cards undrawn were Hourglasses.

The deck should work unupped. I had plenty of quanta for all my plays except for the Miracle, which I ended up playing with 12 quanta (after waiting several turns from when I first could have played it while he hit me with Shockwaves, and while I let him hit me with his weapon for 7 under a Sundial) at the same time I played my second Phase shield, because I was down to 11 life and was afraid he might get three Shockwaves. Without Sundials and with an extra Dimensional Shield there probably wouldn't be a problem there.
