Great concept! I've been really into card games recently and none of them really have the "drafting" or opening a pack experience this game gives. I feel balance was a little off, for example Whirl was consistently a run winner for me, even though it was a 1 cost, but it wasn't a dealbreaker. Art and charm is also a joy, especially the 3D environments and little things such as the cursor being the skeleton's hand. Huge potential in this concept!
