Wow, thanks a lot! You calling it fun and impressive is quite the compliment 😁
As it is right now, I'm not fully satisfied with the layout of the play area, you raise a valid point that the cards are hard to read quickly. My choice to explain everything in real time during gameplay left me with less space, so the played cards are smaller than I'd like. Moving the tutorial away from the main game view will declutter the field and make the cards bigger with more room for text. Also, the battles will be more detailed, by showing how much damage is inflicted where exactly.
Piercing is that good, excess killing damage is dealt to the opponent! To compensate for that, the megaphone has less health, but the Iron is arguably one of the best cards, especially played at the beginning of the game.
Thanks again for playing!
