/**
* 702.47. Ninjutsu
*
* 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.
