Also adding another one. In the picture below, the game isn't letting me play any cards from my hand. I used deck swap to change my hand for the discard pile, but after playing the card, the game doesn't let me play the knife cards but lets me play the shield and draw two card. I can't understand this situation.
I'm pretty sure I remember this being different before, so I infer this is a (very reasonable) balance update. However, after this change, some cards like deck swap, resurrection, and bent arrow become almost useless except under very, very specific circumstances.
I would gently suggest those cards may require revision.
Adding on to my previous reply that I played deck swap again, and now the game softlocked me here since I can't play any cards at all in this picture after my hand got swapped with the discard pile. This is all from the web browser version of the game in case you need to know what version I'm talking about, and I think its the only one available right now unless I download it.
