It doesn't show in the short-term of a single match like this, but I see the action economy of limited draw power being tricky to work with in the future. With draw power cards being detrimental to yourself to some degree as well, It makes the long-term buildup difficult. You draw more cards the closer to 'bust' you are, but the other cards you have to help you draw cards also get you closer to bust, gradually feeding into itself. It's easily fixed with some smart tactics, but the ability to discard isn't particularly helpful in that regard. If anything, it's foolish to do in the long-term at the moment. As it stands, the only thing I'd really suggest is making a 'reshuffle' option that expends energy, probably make it cost 2 or 3, granted how beneficial it can actually be in the long-term.
Woof, I just wasted my time making an uneducated assumption on game design. Hope it helps somehow, and I'd love to see where this goes.
