Flash - Grand Advent: During Advent (Either Attack Step) By either sending your to the Trash, or putting a core from your Grandwalker Nexus to a Spirit you control, stack this from your hand onto your target spirit.
Absolute Release: 4 [LV1][LV2][LV3] (When Advents) Refresh three Spirits you control. Then, when advented onto an "Absolute" family Spirit, if it's your Attack Step, you can put four cores from your "The Grandwalker Zeus-Lolo" to your Spirits. When you've done so, target one card on the opposing Hand/Removed Zone. Discard all other cards.
