*
* 702.97. Cipher
*
* 702.97a Cipher appears on some instants and sorceries. It represents two static
* abilities, one that functions while the spell is on the stack and one that functions
* while the card with cipher is in the exile zone. "Cipher" means "If this spell is
* represented by a card, you may exile this card encoded on a creature you control"
* and "As long as this card is encoded on that creature, that creature has 'Whenever
* this creature deals combat damage to a player, you may copy this card and you may
* cast the copy without paying its mana cost.'"
*
* 702.97b The term "encoded" describes the relationship between the card with cipher
* while in the exile zone and the creature chosen when the spell represented by that
* card resolves.
*
* 702.97c The card with cipher remains encoded on the chosen creature as long as the
* card with cipher remains exiled and the creature remains on the battlefield. The
* card remains encoded on that object even if it changes controller or stops being
* a creature, as long as it remains on the battlefield.
*
* TODO: Implement Cipher as two static abilities concerning the rules.
