Whetstone

Text:

: Each player puts the top two cards of their library into their graveyard.

Rulings:

• 10/4/2004 Can be used if a player has less than 2 cards in their library. It will remove 0 or 1 cards if that is all that is available.
• 10/4/2004 It is not a draw effect so it will not cause a player with less than 2 cards in their library to lose.
• 10/4/2004 Since you are putting more than one card in the graveyard at one time, each affected player can choose the order the 2 cards go in.
