Subject: [PATCH] - Experimental: determineLeftoverMana should use the root
 ability (with the actual mana cost), otherwise it's not always possible to
 determine the correct mana cost (e.g. for Banefire) and PayX gets set to the
 wrong (usually too high) value, making the AI unable to play the card.
