im not sure if this was intentional or not but if you get the card forges, which can give you one energy on discard (basically making it a free discard) but when you have multiple of them and use a card that gets rid of your hand, you are given a few extra crads and energy (amount depends on how many card forges you have, 1 gives 1 card and energy, 2 gives 2 and so on) not sure if this was intetional but it makes for some fun gameplay
