You might be a bit short of death quanta, although I'd have to playtest the deck to be sure. If it turns out you are, I'd change some towers into water pendulums. You've also only got 10 towers, and while you aren't using a lot of quanta, you might need a bit more than that, particularly with the octopus congeal ability. I think I'd either turn the congeals into towers, or turn both octopus into congeal or other cheap quanta card, maybe chrysaora/physalia.
Just out of curiousity, are the poisons/chrysaoras deliberately unupped, or did you run out of electrum? The chrysaora avoids fire shield/thorn carapace/antimatter, but loses the 2 attack, and poison loses 1 damage but is also 1 quanta cheaper, which with only a mark powering death quanta is important. Normally I prefer physalia to chrysaora since the 2 attack is better against the vast majority of decks, but there are cases where chrysaora is better.
