Fun House Mirror

Enchant target creature an opponent controls.
During your opponent's upkeep, enchanted
creature becomes tapped. It can not be untapped
by any spells or abilities.
During your upkeep, gain control of enchanted creature. It untaps, and gains haste during your
turn.
Your opponent regains control of enchanted
creature during your end step.
(These abilities stay in effect until either the creature
leaves the battlefield, or the enchantment is destroyed.)
