In tournament pregame setup, does 'presenting your deck' mean allowing the opponent to shuffle it, or does it mean showing them the contents of your deck and sideboard?

Ruling: Presenting your deck means showing it to your opponent so they have the option to shuffle it. You do not reveal its contents.

Nuances:

• This step allows players to indicate they have the correct number of cards
• For pre-sideboard matches, it confirms decks are in their original configuration
• Players may request a judge perform the shuffle instead of their opponent
