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

Description

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 their 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]. Activate this ability only if seven or more cards are in your graveyard"; or Threshold — [static ability], [self-replacement], [activated ability] and/or [triggered ability]. Activate this ability only any time you could play a sorcery, and only if seven or more cards are in your graveyard."

Several related "threshold mechanics" allow a card to swap between various states based on some external criteria somewhere in the game.

Rules

From the glossary of the Comprehensive Rules (June 7, 2024—Modern Horizons 3)

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 in the Oracle card reference.

Rulings

• Instants and sorceries with threshold check if seven or more cards are in your graveyard when they resolve, not when they're casted 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 activated 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.
