We could tell what each of the other Aquarius Actions was supposed to do to the Dragon, but it wasn’t clear what Shuffle Hands would do, based on the art.
A: The intention is that the Aquarius (AQ) Dragon should work exactly like the Silver Dragon in Seven Dragons (7D), so, by extension, since the 7D promo card Shuffle Hands depicts the Rainbow Dragon art (and the instructions included with the Shuffle Hands 7D promo say that it turns the Silver Dragon wild) the Aquarius Dragon is turned fully Wild by the Shuffle Hands action in Aquarius.
When Aquarius was designed the original five actions clearly mapped to the five elements. When we added the sixth action (Shuffle Hands) there were no extra elements to map it to, so we used the “long hair babe” and a generic Aquarius landscape.
Then, when we made Seven Dragons, the whole concept of having the action-color map to a change of the Silver Dragon was new. Also, we did not include the sixth action, Shuffle Hands, but we made it as a promo card, and the obvious art was the sixth available dragon, the Rainbow Dragon, hence it’s obvious effect on the Silver Dragon was to have it go wild again (which is pretty powerful, and one of the reasons we made it a promo card instead of including three of them like there are in Aquarius).
Then we retroactively applied the Silver Dragon and it’s qualities to AQ, but the art on the AQ Shuffle Hands action was never intended to map explicitly to a particular element, so unfortunately, it’s not clear from the art what it does to the AQ Dragon.
