Ninjutsu {4}{U}{B} ({4}{U}{B}, 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. You may cast a spell from among those cards without paying its mana cost.

每当静刃邪鬼对任一牌手造成战斗伤害时，检视该牌手的手牌。你可以从这些牌之中施放一个咒语，且不需支付其法术力费用。

如果你以「不需支付其法术力费用」的方式来施放牌，则你无法选择支付其替代性费用来施放之，例如呼魂或变身异能所提供的替代性费用。如果该牌的法术力费用中包含{X}，则X必须为0。不过，你可以支付可选的额外费用，例如增幅；而且你仍须支付其强制的额外费用，例如投掷上的费用。
If you cast a card without paying its mana cost, you can't choose to cast it for any alternative costs, such as evoke or the alternative cost provided by the morph ability. If it has {X} in its mana cost, X must be 0. However, you can pay optional additional costs, such as kicker, and you must still pay mandatory additional costs, such as the one on Fling. -

如果你以此法施放永久物咒语，则它会在结算时由你操控地进场。如果你以此法施放瞬间或法术咒语，则该牌会在结算时进入其拥有者的坟墓场。
If you cast a permanent spell this way, it will enter under your control when it resolves. If you cast an instant or sorcery spell this way, that card will be put into its owner's graveyard when it resolves. -

你利用该触发式异能施放的非地牌，是在该异能结算的中途一并施放。不会受到牌张类别的施放时机限制。其他的限制则不会被忽略，例如「只能在对手的回合中施放[此牌]」等。
The nonland card you cast via the triggered ability is cast as part of the resolution of that ability. Timing restrictions based on the card's type are ignored. Other restrictions, such as "Cast [this card] only during an opponent's turn," are not.
