Stengel, Master of Investments

Each time you cast an instant or sorcery spell, you may pay 1{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 creature without paying its mana cost.)
