(Sorry if this has already been discussed. I expected to see it somewhere but searching didn't turn anything up for me.) Frequently a card like Hit The Deck will cause other cards in your hand, in this case move and move/attack cards, to be unable to be played. Unfortunately, there's no feedback about this. It's really easy to lose track of the fact that your warrior used Hit The Deck earlier in the fight and then spend a few seconds clicking some move card only to have it not be usable. I'm envisioning something like fading the cards to grey and showing the preventing card as attached to that card. Thoughts?
