Cool I thought I was right in remembering that. I really ought to know I spent over 500 hours on one file of FFVIII and had every card in the game and the only rules in the world were: Open, Same Wall, with the trade rule being Diff. Essentially that meant everywhere in FFVIII had just one rule, Open since Same Wall cannot be in play without Same. Btw, Lunar rules are an absolute bitch to get changed prior to going in to space and in space you can't do it, still totes worth doing it so Ellone was pushover for the Laguna card.
