Creature - Sliver 2/2, WU (2) All Slivers have shroud. (They can't be the targets of spells or abilities.)1 Bred as living shields, these slivers have proven unruly-they know they cannot be caught.
Illus. L. A. Williams
This card makes slivers in play untargetable. What this means is that no spell or ability with the word "target" in its text can be announced with a Sliver in play as the target. If the spell or ability does not use the word "target", then Crystalline Sliver does not protect the slivers from it. It is very important to remember that cards can be affected without targeting them! [D'Angelo 1998/06/11] For example, none of the Slivers use the word "target" when granting Sliver abilities.
The ability only applies while this card is in play. [D'Angelo 1999/06/02]
