Sideboards are allowed but you have to list the cards in it, along with your main deck.

&

The first match of the best 2-out-of-3 format must be your proper deck, pre-sidedecked.

I would suggest having a few ready-made pre-sidedecked Decks in your BFA Deck Library beforehand, so as to not hold up the time.

As for your submission on the 8th, Okay. But don't come complaining if the names are booked up. As stated, the first 16 people to declare their intent & show me their decklist are the 16 people properly registered in the tournament.

I just want to make that clear.
