At the beginning of your upkeep, put the top ten cards of your library into your graveyard.
Whenever you roll, target player puts the top ten cards of his or her library into his or her graveyard.
10/1/2009 A plane card is treated as if its text box included “When you roll , put this card on the bottom of its owner’s planar deck face down, then move the top card of your planar deck off that planar deck and turn it face up.” This is called the “planeswalking ability.”
10/1/2009 A face-up plane card that’s turned face down becomes a new object with no relation to its previous existence. In particular, it loses all counters it may have had.
10/1/2009 The controller of a face-up plane card is the player designated as the “planar controller.” Normally, the planar controller is whoever the active player is. However, if the current planar controller would leave the game, instead the next player in turn order that wouldn’t leave the game becomes the planar controller, then the old planar controller leaves the game. The new planar controller retains that designation until he or she leaves the game or a different player becomes the active player, whichever comes first.
10/1/2009 If an ability of a plane refers to “you,” it’s referring to whoever the plane’s controller is at the time, not to the player that started the game with that plane card in his or her deck. Many abilities of plane cards affect all players, while many others affect only the planar controller, so read each ability carefully.
10/1/2009 If you don’t have ten cards in your library, you’ll put all the cards in your library into your graveyard. The same is true if the targeted player doesn’t have ten cards in his or her library.
