What does "scry N" allow a player to do?

"Scry N" allows a player to look at the top N cards of their library and then put any number of those cards on the bottom of their library, with the remaining cards being placed back on top in any order. This means that a player has the opportunity to manipulate their upcoming draws by selecting which cards they want to keep on top or move away.

In the context of the options provided, the correct choice captures the essence of the "scry" mechanic perfectly. Scry enables both the examination of the top cards and selective placement, which is valuable for strategizing future turns and enhancing the drawing potential of the player.

The other options do not accurately represent the mechanics of "scry." For instance, stating that a player can only place cards on the bottom without specifying that they can also reorder some on top misses a key aspect of the mechanic. Similarly, mentioning actions such as shuffling cards back into the library inaccurately describes what scry allows. The correct answer encompasses the complete process involved in scrying, highlighting the versatility and tactical advantage it provides a player.
