The idea could be really cool if pushed a bit further, but a few things didn't quite work for me. The actions feel a bit too fast, which doesn't leave enough time to anticipate your next move and results in card spamming, which is actually how I won!
To fix this, I see two possibilities: either extend the card durations to give players time to think ahead, or treat time as a resource that cards consume, letting players take their time with decisions, though that changes the core concept a bit! Nice effort overall
