Summoner of the Tides

Devoid (This card has no color.)
Ingest (Whenever this creature deals combat damage
to a player, that player exiles the top card of their
library.)
{3}{u}, {t}: Put three +1/+1 counters on target
land you control. It becomes a 0/0 Elemental
creature with haste, islandwalk and "{t}: Add {c}" instead of their mana abilities.
It's still a land.
