[Summon Condition: Controlling at least one Winged Beast Spirit/Ultimate]
When summoning this revealed card, ignore the Summon Condition.
Release: 3 [LV3][LV4] (When Attacks) You can reveal three cards from the top of your deck. You can pay one cost to summon one "Winged Beast" family card among them. Remaining cards are returned to the bottom of your deck. When this effect summons an Ultimate, send an opposing Life to the Reserve. Also, by putting three cores from any Green Grandwalker Nexus(es) you control to this Ultimate, this Ultimate refreshes.
Ruling:
1. If this Ultimate's Release doesn't summon an Ultimate, you can't move three cores from Grandwalker Nexus(es) to this Ultimate, hence it can't refresh.
2. Core Charge and any other effects only activate after this Ultimate's Release finishes its activation.
