For those wondering what the “Royale Rules” are, the rules used in the video series for each Duel are that players have 4000 LP, the player going first gets to draw, and the players can only use the preconstructed Decks (which of course means disregarding the current Forbidden/Limited List). The tournament structure has 2 player blocks, A and B, each of which plays in a Round-Robin format (i.e. everyone plays against everyone in the block), then the #1 player of each block face each other in a final Duel. In case of a tie between wins/losses, determine the winner by LP difference.
