So really... what is Aquapolis? Here are the facts:
Set Size: ??? in Japan, 182 in the US
Set Order: 15th and 16th set in Japan, 14th set in the US
Release Date: March 8th, 2002 and May 24th, 2002 in Japan, January 15th, 2003 in the US.
The release date was pushed back a little bit from late December to mid-January a few times.
The Japanese name for Card-E 2 is loosly translated to "The Lost City".
The English release of Aquapolis actually mixed the Japanese release of both Card-E 2 and Card-E 3 into one huge set. 182 cards. Why this happened... it looks like Wizards wants to rush out the next few sets, for some reason. Hmmm...
This set also is the first to seperate the Holo-Rares from the rest of the set; they're numbered differently from the other rares.
This set is also the first set to introduce "Crystal" Pokémon to the set.
The symbol for Aquapolis is a temple in a water droplet.
