* Ninja Strike 4
(Whenever one of your opponent's creatures attacks or blocks, if you have 4 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, one of your creatures gets "blocker" until the start of your next turn.
