- * 702.64. Delve
- *
- * 702.64a Delve is a static ability that functions while the spell that has delve is on
- * the stack. "Delve" means "As an additional cost to cast this spell, you may exile any
- * number of cards from your graveyard. Each card exiled this way reduces the cost to cast
- * this spell by {1}." Using the delve ability follows the rules for paying additional
- * costs in rules 601.2b and 601.2e-g. #
- *
- * 702.64b Multiple instances of delve on the same spell are redundant.
- *
+ * 702.65. Delve
+ * 702.65a Delve is a static ability that functions while the spell with delve is on the stack.
+ *         “Delve” means “For each generic mana in this spell’s total cost, you may exile a card 
+ *         from your graveyard rather than pay that mana.” The delve ability isn’t an additional
+ *         or alternative cost and applies only after the total cost of the spell with delve is
+ *         determined.
+ * 702.65b Multiple instances of delve on the same spell are redundant.
+ * 
+ * * 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.
+ * * 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.
+ * 
  * @author LevelX2
  *
+ *  TODO: Change card exiling to a way to pay mana costs, now it's maybe not passible to pay costs from effects that 
+ * increase the mana costs.
