Legendary Creature — Octopus 8/8, 5UUU (8)
Mythic Rare
Whenever Lorthos, the Tidemaker attacks, you may pay {8}. If you do, tap up to eight target permanents. Those permanents don't untap during their controllers' next untap steps.
When Lorthos emerges from his deepwater realm, the tides bow to his will and the coastline cowers in his presence.
Illus. Kekai Kotaki

10/1/2009: You may target any eight (or fewer) permanents. It's okay if any of them are already tapped, and it's okay if any of them are controlled by someone other than the defending player.
10/1/2009: If a targeted permanent is untapped at the time its controller's next untap step begins, this ability has no effect on it. It won't apply at some later time when the targeted permanent is tapped.
10/1/2009: If an affected permanent changes controllers before its old controller's next untap step, this ability will prevent it from being untapped during its new controller's next untap step.
