Really well done but often you are in situations where the game wants you to play a certain card which you do not have in hand.
You should be able to play one of the cards in your hand (especially the cards with abilities related to discarding) to obtain the card you need. Moving on to the next situation after one card is played makes the entire game chance based, dependent on what cards are drawn into your hand. If you could actually utilize the discard abilities without being "punished" for playing the "incorrect" card that the situation called for, then then the player could fully engage with all the ideas that you all came up with.
Really creative idea, the theming of judging the dead works well with the strategic mindset that a card game (and/or deck building game) evokes.
