Rule 424.3

This action is formatted as "Reveal cards from [zone]." or “Reveal [Zone].” Example: "Reveal 2 cards from the top of your Main Deck" would be executed by taking the two cards from the top of your Main Deck, and then presenting them to all players to clearly read and understand at the table. Then, when all players have had a chance to understand the revealed information, return them to the top of the Main Deck in the same order.
