The following ruling Q. Can I use Rare Candy to evolve Pichu into Raichu EX? A. No, Rare Candy states if you have a card that "Evolves From" your Pokemon. Pikachu does not say that it "Evolves From" Pichu, so Rare Candy will not work in this situation. (Sep 11, 2003 PUI Rules Team Meeting) Is being interpreted as saying you can not use rare candy with any EX pokemon. For example, you can not evolve a aron with a rare candy into an aggron ex (or ralts into a gardevoir ex) Is this the correct intepretation?
