The Mystic Fountain was released on the 24th May 2013 for 350 Credits each and there were 180 units. It was only available via the Catalogue for a period of time during the Mystics campaign. It was a release of a recoloured, old school rare, which hadn't been done since the Bronze Pillow and Silver Pillow were released in January 2013.
Similarly with other Limited Edition Rares, as soon as a player bought it they were trying to resell it for less than its purchase value, ultimately making it fail. The description for the item was 'This thing doesn't just squirt water!'
