Lorthos, the Tidemaker
Commander 2014 — Mythic
Legendary Creature — Octopus
Whenever Lorthos, the Tidemaker attacks, you may pay . 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.
