Flash - Advent: Winged Beast & Cost 5 or more (Either Attack Step)
By sending your Soul Core to the Trash, stack this from your hand onto your target spirit.
[LV1][LV2][LV3] Whirlwind: 2 - (When Summoned/Advents) Heavy exhaust 2 opposing Spirits/Ultimates. (Heavily exhausted cards are turned upside down and become exhausted after refreshing once.)
[LV2][LV3] (When Attacks) At the end of battle, by paying 2 costs, refresh this Spirit. When refreshed by this effect, once per turn, send 1 opposing Lives to the Reserve.
Ruling:
With this Spirit's [LV2][LV3] effect, if this Spirit goes down to Lv1 after paying cost, it cannot decrease opposing Life by the same effect.
