[LV1][LV2][LV3] (When Attacks) During this turn, one opposing Spirit/Ultimate gets -5000 BP. For each Yellow Spirit you control, activate this effect once, and Spirits/Ultimates whose BPs are brought to 0 by this effect are destroyed.
[LV2][LV3] Flash - You can put four cores from any Yellow Grandwalker Nexuses you control to the Void. When you've done so, during this turn, the [LV1][LV2][LV3][LV4][LV5][LV6] BP of opposing Spirits/Ultimates becomes 1000 BP.
