Éphémère
Contrecarrez le sort ciblé qui cible un permanent que vous contrôlez.
Piochez une carte.
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.
