Target player discards a card.
Cipher (Then you may exile this spell card encoded on a creature you control. Whenever that creature deals combat damage to a player, its controller may cast a copy of the encoded card without paying its mana cost.)
Rulings (11)
If you want to encode the card with cipher onto a noncreature permanent such as a Keyrune that can turn into a creature, that permanent has to be a creature before the spell with cipher starts resolving. You can choose only a creature to encode the card onto.

If the spell with cipher doesn’t resolve, none of its effects will happen, including cipher. The card will go to its owner’s graveyard and won’t be encoded on a creature.

You cast the copy of the card with cipher during the resolution of the triggered ability. Ignore timing restrictions based on the card’s type.
