I created the scorpionbow thing in the rainbow forums, and there's a few things I've noticed as I play it. One, adding sundials was very useful since the deck is more of a poison stall. And the poison really doesn't go very fast if you can't get an early dune scorpion, so I might add one more of those if I were you. Also, I don't know how well you can play blessings and if you feel quanta-starved for light since I haven't played with your deck, but you might want to consider taking a couple out and replacing them with adrenaline and/or another momentum or two.
