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) (

discardTo discard a card, move it from its owner’s hand to that player’s graveyard.
By default, effects that cause a player to discard a card allow the affected player to choose which card to discard. Some effects, however, require a random discard or allow another player to choose which card is discarded.
If a card is discarded, but an effect causes it to be put into a hidden zone instead of into its owner’s graveyard without being revealed, all values of that card’s characteristics are considered to be undefined. If a card is discarded this way to pay a cost that specifies a characteristic about the discarded card, that cost payment is illegal; the game returns to the moment before the cost was paid (see rule 733, “Handling Illegal Actions”). (CR 701.9) a card unless this creature entered this turn.
