Them's the Rules

Detain target creature. Splice onto enchantment {w/u}{w/u}{w/u}. (When detained, target creature cannot attack or block and its activated abilities can't be activated until your
next turn. To splice
onto a spell, pay the slice cost and reveal this
card from your hand. Add this card's effects to
the casted card. You can only splice
this card onto enchantments.)
