You are trying to win the game in one turn, ideally your opponent won't have many starting pokemon, ie 1-3, if its more winning will be very difficult, the first thing to do is too get out forrest of giant plants of broken time space, these will help you get out shiftrey. Then after this you will play cards until you double evolve shiftry, and using cards in the deck, keep drawing and scooping your pokemon until all opposing pokemon are in the opponents deck.
