■ Ninja Strike 1
(Whenever one of your opponent's creatures attacks or blocks, if you have 1 or more cards in your mana zone and if during that attack you didn't use a "Ninja Strike" ability, you may summon this Shinobi for no cost. At the end of the turn, put this Shinobi on the bottom of your deck.)
■ When you put this creature into the battle zone, choose one of your opponent's creatures in the battle zone and tap it.
