Proclaim: Decisive Point
■ You may only cast this card if you have an «Astrodragon» on your field. ■ Draw a card, and for this turn, all «Astrodragon» on your field cannot be destroyed or returned to hand by your opponent's card effects, and they get power+3000! You may only cast "Proclaim: Decisive Point" once per turn.
Come what may, my victory is guaranteed.
