Threshold

Threshold is a characteristic-setting ability. An object with threshold has the text after "Threshold -" if its controller has seven or more cards in his or her graveyard. Otherwise, the text after "Threshold -" is treated as though it did not appear on the object. An instant or sorcery with threshold has the threshold text only if it's on the stack. An artifact, creature, enchantment, or land with threshold has the threshold text only if it's in play. See rule 502.23, "Threshold."

Threshold

Threshold used to be a keyword ability. It is now an ability word and has no rules meaning. All cards printed with the threshold keyword have received errata. Updated wordings are available in the Oracle card reference.
