I love the theme, and the execution so much. I cannot stress enough how helpful it is to see how the dam taking hits works! Being able to visualize it in that way reeeeeally bring the faction to life!
I think if you wanted to save a bit on board space, you could move your diagram of how the dam taking hits works to a separate card, but I think it's up to your opinion. You're doing well on space and board layout already, just think that once you've got a few games under your belt, that info might be important for other factions to see!
Still though, the card layouts, abilities, and thematics are all super unique and the heart and theorycrafting really shine through on this one! :D
