+ *
+ * 702.47a Ninjutsu is an activated ability that functions only while the card 
+ * with ninjutsu is in a player's hand. "Ninjutsu [cost]" means "[Cost], Reveal 
+ * this card from your hand, Return an unblocked attacking creature you control 
+ * to its owner's hand: Put this card onto the battlefield from your hand tapped
+ * and attacking."
+ *
+ * 702.47b The card with ninjutsu remains revealed from the time the ability is
+ * announced until the ability leaves the stack.
+ *
+ * 702.47c A ninjutsu ability may be activated only while a creature on the
+ * battlefield is unblocked (see rule 509.1h). The creature with ninjutsu is
+ * put onto the battlefield unblocked. It will be attacking the same player or
+ * planeswalker as the creature that was returned to its owner's hand.
