Barl's Cage

Artifact, 4 (4)
{3}: Target creature doesn't untap during its controller's next untap step.¹
For a dozen years the Cage had held Lord Ith, but as the Pretender Mairsil's power weakened, so did the bars.
Illus. Tom Wänerstrand

Gatherer Card Rulings [Nov 2009]

• 10/4/2004: Affects the next untap of that creature for whoever controls it at that time. In other words, the effect does not remember the current controller.
• 10/4/2004: Does not prevent a creature from untapping at other times. It just stops the "normal" untap during the untap step.
