Easy Money Trick: One of the best way to gain money is to do secondary missions over and over again, one mission called "Mike's Revenge 1, 2, & 3" gives you a good amount of gold, to beat it Equip the character slot with "Mike" type of character, boxer class, this will serve as the tank because Mike is resistant to strike and have lots of HP. For the rest of the team, equip poison weapons. Wait till you have lots of mana, and start sending your army. Keep sending your tanks, followed by the rest of the team. If your tank die, send more of em. Easy money. :)
Multiple copies of card is not sorted properly, I suggest adding a "Card Collection Book" which shows numbers of cards in your inventory by displaying a number next to the cards.
