Hi! I've been noticing a problem with using the altars- I change one card and sacrifice 2 more like normal, but at least some of the time, the resulting card never is added to my deck. I'm going to keep track of the number of occurrences for you in a reply- I don't believe this problem was happening when I played yesterday, but I'm not certain.
Also, I saw below that at one point, your intention was for the altar to use 1-3 cards sacrificed to get the new card, but now it always uses 2. Is this on purpose?
Anyway, thanks for making this game! I'm excited to see how it progresses
