Forum:Grave of the Super Ancient Organism vs. Stardust Dragon

Say,

Player 1 : Has one face up 'Grave of the Super Ancient Organism' Player 2 : Has one face up 'Stardust Dragon'

Player 1 : Activates 'Lightning Vortex'

can Player 2 tribute Stardust Dragon to negate 'Lightning Vortex', or does 'Grave of the Super Ancient Organism' prevent it from doing so?
