Threshold

Threshold is an ability word that gives a card different or additional characteristics if its controller has seven or more cards in his or her graveyard. It was introduced in Odyssey.

Threshold can be many things, but the common thing is that it is active when the controller of the card with threshold has seven or more cards in his or her graveyard. It's written either "Threshold — As long as there are seven or more cards in your graveyard, [static ability], [self-replacement], [activated ability] and/or [triggered ability]"; or "Threshold — [static ability], [self-replacement], [activated ability] and/or [triggered ability]. Play this ability only if seven or more cards are in your graveyard"; or Threshold — [static ability], [self-replacement], [activated ability] and/or [triggered ability]. Play this ability only any time you could play a sorcery, and only if seven or more cards are in your graveyard."

Rulings

• Instants and sorceries with threshold check if seven or more cards are in your graveyard when they resolve, not when they're played or put on the stack.
• Activated and triggered abilities that permanents have at threshold check the number of cards in your graveyard only when the abilities are played or triggered. Even if you have fewer than seven cards in your graveyard when an ability resolves, that ability will resolve normally.
• Static threshold abilities are simply "on" when you have seven or more cards in your graveyard and "off" when you don't.
