When this card was either revealed by the effect of your "Godseeker SkyBird Bathura Pheasant" or sent to the Trash by the effect of your "The Grandwalker Horus," 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 - Exhaust three opposing Spirits/Ultimates. Then, by sending two cores from your The Grandwalker Horus to the Void, return an opposing exhausted Spirit/Ultimate to the Hand.
