DD51 is going to be removed by DD52.
I play cards irl on regular basis, but when it comes to digital card games, I cannot say I am into spins on them. You still did a good job, but I think the bottom half of your game is more interesting than the top, if you get what I mean. I hope the video is going to be useful to you.
