Threshold — Put three cards from your graveyard on the bottom of your library: Battlefield Scrounger gets +3/+3 until end of turn. Activate only once each turn and only if seven or more cards are in your graveyard.

Check the number of cards in your graveyard before activating the ability. If activating the ability causes that number to fall below seven, the ability still resolves as normal.
