NinjutsuNinjutsu 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.”
The card with ninjutsu remains revealed from the time the ability is announced until the ability leaves the stack.
The creature put onto the battlefield with the ninjutsu ability enters attacking the same player, planeswalker, or battle as the creature that was returned to its owner’s hand.
Commander ninjutsu is a variant of the ninjutsu ability that also functions while the card with commander ninjutsu is in the command zone. “Commander ninjutsu [cost]” means “[Cost], Reveal this card from your hand or from the command zone, Return an unblocked attacking creature you control to its owner’s hand: Put this card onto the battlefield tapped and attacking.” (CR 702.49) (
, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.)
Whenever this creature deals combat damage to a player, look at that player's hand.
: Return target Ninja you control to its owner's hand.
ActivateTo activate an activated ability is to put it onto the stack and pay its costs, so that it will eventually resolve and have its effect. Only an object’s controller (or its owner, if it doesn’t have a controller) can activate its activated ability unless the object specifically says otherwise. A player may activate an ability if they have priority. See rule 602, “Activating Activated Abilities.” (CR 701.2) only during your turn.
