I find it hard to believe this deck is PVP1....
It's probably unnecessary to use Mindgate. If you're looking to get more cards, Electrum Hourglass is a better choice. Also, Precognition might be an even better choice than that, though you won't gain card advantage that way; it depends on how fast games are.
Because of the Entropy emphasis of SoSe, Entropy mark is probably more useful than Aether Mark, and will let you use the ever-lovable Supernova. If you want to keep using Mark of Aether, consider Phase Shields, since you have no shield in the deck right now.
Looks flooded in quanta (16 quanta sources). If you use Supernova/Entropy Mark, it'll be even more flooded. Perhaps replace some Novas/Quantum Towers with CC; Thunderbolt's an excellent card, and with the Mark of Aether (assuming you keep the Mark of Aether), you'll never have problems playing it. Alternatively, some cheap damage sources like Graboids would help in case all your SoSe derp majorly and give you 18 Amethyst Towers or something like that.
