I love the artwork and the thematics of these guys a ton... Having no hand because they're snakes? So cool!
One thing I'm wondering about is scoring, since it seems kind of easy for them to lose points, and I'm interested to see how it battles out. When they take the action to score points matching the suit of the die roll matching casinos in a matching clearing, is it just casinos in ONE matching clearing or AMONG matching clearings? It might affect their gameplay a bit depending on that, since that way they can spread out a bit more, and they're not limited to certain clearings in similar ways to the lizards.
Love the deck building mechanic a lot, and as I mentioned before, the artwork is killer!
