Delve is an alternative cost payment keyword ability. It was introduced in Future Sight. At the time, it was only printed on three timeshifted cards and was a cost reduction. It was re-introduced as the clan specific mechanic for the Sultai Brood in Khans of Tarkir.

Rulings

• The rules for delve have changed slightly since it was last in an expansion. Previously, delve reduced the cost to cast a spell. Under the current rules, you exile cards from your graveyard at the same time you pay the spell’s cost. Exiling a card this way is simply another way to pay that cost. [This is similar to the change made to convoke for the Magic 2015 Core Set.]
• Delve doesn’t change a spell’s mana cost or converted mana cost. For example, Dead Drop’s converted mana cost is 10 even if you exiled three cards to cast it.
• You can’t exile cards to pay for the colored mana requirements of a spell with delve.
• You can’t exile more cards than the generic mana requirement of a spell with delve. For example, you can’t exile more than nine cards from your graveyard to cast Dead Drop.
• Because delve isn’t an alternative cost, it can be used in conjunction with alternative costs.
