Text (FS+errata): 2/1, Flying. ; Flash. ; If an opponent would search a library, that player searches the top four cards of that library instead. [Oracle 2009/07/08]
This works if an opponent searches any library, not just their own. [Future Sight FAQ 2007/05/01]
If the search would have the player shuffle the library, the whole library is still shuffled. [Future Sight FAQ 2007/05/01]
