Flash - Advent: Ultraman (Either Attack Step)
By sending your Soul Core(Soul Core) to the Trash, stack this from your hand onto your target spirit.
[LV1][LV2] (When Advents) You can show your opponent cards from your hand which contain "Ginga"/"X" in their names, one of each. For each card revealed, decrease the amount of cards discarded by this effect by -1. Draw two cards from your deck, then discard two cards from your hand.
After you show your cards, they are returned to your hand instead of putting at the Removed From Game Zone.
