Thanks for that tip about the elements! I guessed it would be that simple - but I was not sure if it was hard coded or not

I had figured that the different size boards would require a massive script update - still mabey something for those long boring winter months :P
As for user shops, the reason I suggest this is so people can choose they cards they want to offer to other members rather than the other members randomly offering for any card they wish.
Minumum - Might be useful if someone wanted to battle another person with only say level 5 cards or for use with the random rule! My experience with that is nearly always level 1-3 cards while my opponent gets level 5+ (at least in the ff8 game lol - I havnt tried it out in your hack yet) I think this is because most people have a LOT more of the low level cards
