Rulings

• 2009-10-01
  If the targeted opponent has fewer than thirteen cards in his or her library, that player puts his or her entire library into his or her graveyard.
• 2009-10-01
  The opponent you target doesn't have to be the opponent who searched his or her library.
• 2009-10-01
  If a search effect is affected by Aven Mindcensor's ability (which causes a player to search the top four cards of his or her library instead), that still counts as searching that library.
• 2009-10-01
  A spell or ability causes a player to search his or her library only if it specifically contains the word "search" in its text. For example, if a spell or ability lets a player look at the top four cards of his or her library and do something with one of those cards, that's not a search.
• 2009-10-01
  Archive Trap checks only whether an opponent searched his or her library. It doesn't matter whether that player found a card during the search.
• 2009-10-01
  Effects that increase or reduce the cost to cast a Trap will apply to whichever cost you chose to pay.
• 2009-10-01
  Casting a Trap by paying its alternative cost doesn't change its mana cost or converted mana cost. The only difference is the cost you actually pay.
• 2009-10-01
  You may ignore a Trap's alternative cost condition and simply cast it for its normal mana cost. This is true even if its alternative cost condition has been met.
