This is a card you can add to your Aquarius deck to alter the gameplay to resemble Seven Dragons.
The front of the card is an image of the Aquarius Dragon, and the back of the card contains the instructions on how to use this card. It acts as a new starter card, and is initially wild.
As you play Actions to the discard pile, the Aquarius Dragon changes color to match the top Action card in the discard pile. You can also choose to play an Action to the discard pile without fulfilling the action in order to just change the color of the Dragon. Or you choose can play an Action card to the bottom of the discard pile to get the benefit of the action without changing the Dragon.
