Terror of the Nostromo

Ambush, Menace
If Terror of the Nostromo is to be removed
from play by an instant or sorcery card the
opponent must sacrifice a land
or the spell is countered
If mana from a Host token was spent to cast this
spell Terror of the Nostromo gains double-strike
Perfect Organism... It's structural perfection is
matched only by it's hostility.—Ash
