Each time you cast an Instant or Sorcery spell,
you may pay {p/u}{p/b}. If you do, that spell gains
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.)
