When this card was either revealed by the effect of your "Godseeker HieroglyphCavalry Spotter-Sheneut" or sent to the Trash by the effect of your "The Grandwalker Thoth," you can add it to your hand. When you've done so, put one core from the Void to a Grandwalker Nexus you control.
Flash - During this turn, opposing effects and the attacks of Cost 4 or more Spirits/Ultimates can't reduce your life to one or below. Also, by sending two cores from a "The Grandwalker Thoth" you control to the Void, return an opposing Spirit/Ultimate to the bottom of the deck.
