Delve

Another exam­ple of a key­word that affects the cost of a spell and pro­vides an alter­na­tive way to ease the cost of spells. The only time it has been used is in the Future Set block as a mechanic from some future set.

702.63. Delve

• 702.63a. Delve is a sta­tic abil­ity that func­tions while the spell that has it is on the stack. “Delve” means “As an addi­tional cost to play this spell, you may remove any num­ber of cards in your grave­yard from the game. Each card removed this way reduces the cost to play this spell by {1}.” Using the delve abil­ity fol­lows the rules for pay­ing addi­tional costs in rules 409.1b and 409.1f-h.
• 702.63b. Mul­ti­ple instances of delve on the same spell are redundant.

Rules Trans­la­tion

• 702.63a. — When you’re play­ing the spell, you can remove cards from your grave­yard from the game and for every card you remove in this way it decreases the cost of the spell by one col­or­less mana.
• 702.63b. — Delve does not stack, it’s redundant.
