I played through this 4 times, and thoroughly enjoyed it. As someone that knows a bit about blackjack, it was interesting to see the forge card mechanic. My main strategy was pairing a 10-card with a low card to give the most options when drawing. It is a bit unfortunate that you lose the other 6 cards when forging- as I thought at first I could build a card from 2 of the 4 sitting on the table. I think there should be some kind of indication to the player that you are only picking one card from the options. It was also unfortunate that tying counts as a loss instead of a push, like in traditional blackjack.
Overall I think this game has great potential with some small tweaks. Good job!
