I think you are overlooking axe it doesnt play as nice as compass with amber but playing a resource for free with the draw is huge especially early before you have your deck super slim and i also think you are underestimating kaz (score in particular) it basically solves score in the early rounds letting you focus almost entirely on ore or upgrades and gets stronger as you add cards like geodes that are very cheap and upgrades on them are almost never a waste because you will play them every time you see them similar story on meteorites but not quite as good because they dont replace themselves
