Okay guys, in light of possible EX 12 release while I'm asleep.IF EX 12 comes out before the tourney, you have until the tourney starts to make changes to your files to use them if you wish.
You must resend your file if you make changes to include EX 12 before the tourney starts
EDIT* if you do make changes, make sure the total level of the cards in your file still add 100 according to rules.
If you don't want to include EX12, in which case your file wouldn't be changing, you do not need to resend your file.
Obviously if EX12 doesn't come out before the tourney...ignore this
