If this card in your hand is discarded by the opponent, you can summon it by paying one cost. When you've done so, draw three cards.
[LV1][LV2] (Your Attack Step) When only the opposing Spirit/Ultimate is destroyed by BP Comparison with your "Blade Beast" family Spirit, send one opposing Life to the Trash.
[LV2] Neither player can remove cores other than Soul Core from their Spirits/Ultimates.
