You may look at an additional two cards each time you
surveilTo “surveil N” means to look at the top N cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.
If an effect allows you to look at additional cards while you surveil, those cards are included among the cards you may put into your graveyard and on top of your library in any order.
If a player is instructed to surveil 0, no surveil event occurs. Abilities that trigger whenever a player surveils won’t trigger.
An ability that triggers whenever a player surveils triggers after the process described in rule 701.25a is complete, even if some or all of those actions were impossible. (CR 701.25).
ExileTo exile an object, move it to the exile zone from wherever it is. See rule 406, “Exile.” (CR 701.13) this enchantment:
ShuffleTo shuffle a library or a face-down pile of cards, randomize the cards within it so that no player knows their order.
Some effects cause a player to search a library for a card or cards, shuffle that library, then put some or all of the found cards into a different zone or in a certain position in that library. In such cases, the found cards aren’t included in the shuffle, even though they remain in the library at that time. Rather, all the cards in that library except those are shuffled. Abilities that trigger when a library is shuffled will still trigger. See also rule 401, “Library.”
If an effect would cause a player to shuffle one or more specific objects into a library, that library is shuffled even if none of those objects are in the zone they’re expected to be in or an effect causes all of those objects to be moved to another zone or remain in their current zone.
If an effect would cause a player to shuffle a set of objects into a library, that library is shuffled even if there are no objects in that set.
If an effect causes a player to shuffle a library containing zero or one cards, abilities that trigger when a library is shuffled will still trigger.
If two or more effects cause a library to be shuffled multiple times simultaneously, abilities that trigger when that library is shuffled will trigger that many times.
If an effect would cause a player to shuffle a library at the same time that an object would be put into a certain position in that library, the result is a shuffled library that’s randomized except that the object is in the specified position. (CR 701.24) your graveyard into your library.
