Thought I report a bug on one of the cards in the game. I drafted a card called "Artist's Clay" that duplicates a summoned ally when its played, but after I played it, its removed from my deck for the rest of the run. (It doesn't go into my discard pile when played or ever returned to my deck after the run is over.) The card itself doesn't say that its one-time use, so I can't understand why this is happening.
In addition, the card doesn't show up in my library tab upon clearing the game even thought I found it twice on my last run.
