Draconic Kidnapper

Haste, flying, first strike
When Draconic Kidnapper deals combat damage
to a player you may pay {1}{b}{r} and gain control
of a non legendary creature they control as long
as you control Draconic Kidnapper, that creature
remains tapped as long as you control it.
{1}{b/r}{b/r}: This creature has Menace and +1/+0
until end of turn.
