Legendary Creature — Serpent - (rare)
Trample
Phasing (This phases in or out before you untap during each of your untap steps. While it's phased out, it's treated as though it doesn't exist.)
At the beginning of your upkeep, all lands you control phase out. (They phase in before you untap during your next untap step.)
"Taniwha rolls in its sleep, and the land is awash with the waves."
—Poetics of Hanan
