抓一张牌。
If the permanent you control targeted by the target spell leaves the battlefield, that spell is no longer a legal target for Keep Safe. On the other hand, if that target permanent becomes an illegal target for the target spell but remains on the battlefield under your control, the target spell is still a legal target for Keep Safe.
