Tap target creature an opponent controls. That creature doesn't untap during its controller's next untap step.
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 (13)
If the creature leaves the battlefield, the exiled card will no longer be encoded on any creature. It will stay exiled.

You choose the creature as the spell resolves. The cipher ability doesn't target that creature, although the spell with cipher may target that creature (or a different creature) because of its other abilities.

The spell with cipher is encoded on the creature as part of that spell's resolution, just after the spell's other effects. That card goes directly from the stack to exile. It never goes to the graveyard.
