Artifact, 5 (5)
Rare
{T}: Choose any number of target creatures. Each of those creatures gains persist until end of turn. (When it dies, if it had no -1/-1 counters on it, return it to the battlefield under its owner's control with a -1/-1 counter on it.)
Illus. Ron Brown

5/1/2008: If a nontoken creature that gains persist this way is put into a graveyard, that card will be returned to the battlefield with a -1/-1 counter on it. However, because it's a new object with no relation to its previous existence, the returned creature will not have persist.
