I´ve never seen this character that abolishes special rules in Balamb docks!!! Man, I´ve been living in a hole...
But I highly recomend to play with the hole CCGroup and then go for Queen Card in disc 4, she´s in Esthar Peninsula. You can get all the rare cards from her then: Irvine, Kiros, Doomtrain, Chubby(or Fat)Chocobo, Phoenix and... I think that´s all.
