Regalis Piece (You may only have one Regalis Piece in your deck, and use it a total of one time in a fight.) Play this with COST [Counter Blast (1) or Energy Blast (3)]! Draw a card, remove this card, choose one of your vanguards, and it gets [Power]+15000 until end of that battle. Then, COST [bind a card with the same name as your vanguard from soul or drop], and it gets +25000 instead of +15000. [AUTO]:When this card is discarded from hand while riding from the ride deck, COST [Counter Blast (1) or Energy Blast (3)], draw a card, and remove this card.
