Forcecage

Enchant target creature. Target enchanted
creature gains indestructible and hexproof, and
may not attack, tap, untap, block, or activate any
of its abilities.
The black dragon, so sure of its superiority, spent its
time in combat not flaying her enemies alive, but
escaping an ever-changing series of invisible cages
summoned at that pint-sized sorceress's command.
