Gamble button (wheel) got all your crates in it when you click on a crate, click the bag to open, then flip all 3 cards over. When your ready to battle, go into your inventory, click on a card, and press the green "Add" button. This will add the card to your lineup, the uppermost number is the damage, and the lowermost is the HP. Press the battle button when your ready to battle, and click one of your cards to use it. The "Exit Battle" button will still give you money for the respective wave when clicked.
