Cool idea, a shuffleboard battler. There are some cool concepts but the game lacks some basic feedback for understanding what is going on.
It took me a while to understand I had to shoot 4 to see the results, maybe you could have used the concept of action points, a staple in these kind of battlers. Also shooting 4 from 5 is like leaving only 1 behind, which is not that interesting. Another direction would be to give 4 pucks and allow players to shoot them all, but the results are changed based on how many stuff it hit as well, like card effects that can change based on how you play the puck. Like the healing egg now. For example, there could be red pins on the board, and attack pucks gain +1 atk for the amount of pin hits, but loses 0.5 for wall hits, stuff like that. So the decision is not about which one to leave out, but the order and how you throw them.
Overall cool concept, nice work
