Dr. Strange

Flying
{w}: Tap or untap target permanent.
{2}{r}: Deal 5 damage to target creature.
{4}{b}: Search you library for a card and put that
card into your hand.
{6}{u}{t}: Take an extra turn after this one.
Dr. Strange does not untap during your next
untap step, and cannot be untapped during your
next turn.
I've come to bargain.
