With the SN nerf, I no longer see it as viable to ai3 compared to other decks, but I would consider it a strong contender against Bronze. So after a long-thought and short-tested analysis, I've made a few (actually, a lot) of changes to the deck:
PC is a must. This is the simplest way to put it in.
Demon and nymph do essentially the same thing, dealing with high-attack creatures. Maybe one more swap is an option.
Similar concept, swapping CC cards. Octopus proved very useful in cases where a Uli would not have.
Two Octopi is better than one, but Poseidon is still a huge threat when you draw it early.
Essentially this makes it a cross of original deck and Gandora's second variant. There's two more changes I'm considering:
Steammie proved useful in a decent amount of games, but I think a pendulum would have helped more in the other games. I felt underquanta'd a lot, but it probably had just as much to do with not being able to play multiple supernovas first turn.
Getting them on the first turn could be a better trade off for more base stats. I didn't test it, however.
