Reason why i tag this as meta is because it is an option to be able to play past the Dragon Buster lock, since you dont really need to summon from the extra deck.
Main strategy is to cycle cards in hand to get perfection and others on the field. Best opening card is diviner, and pitching Arc to search whatever missing piece you have. If you have a combination of Idaten, Benten, or Machine Angel Ritual, summon Idaten by pitching Benten, then search dawn via idaten and perfection via benten. If you are leading into this from the diviner play, you can add absolute and vrash to get vrash on the field with 4000 atk. Also cycling idaten tributes, via ritual or merciful, will get you big walls/beat sticks with Perfection and Vrash. Quick note: Learned this the hard way, but Natasha can only use GY effect after being ritual summoned.
