Get A Promo Lv.9 Slowpoke
Take 59 of your ENERGY cards and 1 basic pokemon and make a deck with them. Select the deck as your dueling deck. Then go talk to the boy in the Fire Club. He will ask you to give him all your unused ENERGY cards. Tell him Yes. If you tell him No, he will go away and not come back. Then you can't get the Slowpoke.
