Improve UX for cards in hand #12
Description
The current rendering behavior for cards in the users hand is very basic. We could improve it dramatically by adding some of the following (largely copying MTGA behavior):
- The "preview" that renders by default should include some useful information (card name, mana cost, card art?)
- When the user hovers over a card preview, it expands and renders the entire card, which disappears after the cursor leaves the frame of the card preview
- Cards in hand are draggable and can be re-ordered
- Cards in hand can be cast by dragging them and dropping them onto the battlefield
